Find the value of the expression (4x−12)+(12xy−10)(4x-12)+(12xy-10) for x=4 and y=6
Answer:
398 ( did it on college bridge)
Step-by-step explanation:
The required value of the expression is 412 which is determined by substituting for x = 4 and y = 6.
What is the algebraic expression?Unknown variables, numbers, and arithmetic operators make up an algebraic expression. It contains no equality or inequality symbols.
The expression is given in the question as:
(4x−12)+(12xy−10)(4x-12)+(12xy-10)
To find the value of the expression for a given value of x and y, we can substitute the values of x and y into the expression and evaluate it.
(4x−12)+(12xy−10)(4x-12)+(12xy-10)
Substituting x=4 and y=6 into the expression, we get:
(4(4)−12)+(12(4)(6)−10)(4(4)−12)+(12(4)(6)−10)
This simplifies to:
(16−12)+(12(24)−10)(16−12)+(12(24)−10)
This further simplifies to:
4+(12(24)−10)(4)+(12(24)−10)
4+(12(24)−10)(4)+(12(24)−10)
4+288+120 = 412
Therefore, the value of the expression for x = 4 and y = 6 is 412.

Jamie unfolded a cardboard box. The figure of the unfolded box is shown below: Which expression can be used to calculate the area of cardboard, in square inches, that was used to make the box? 6 x 4 x 4 4 x 6 x 6 6 x 2 x 2 2 x 6 x 6
there are 6 sections and the sections are 4 x 4
so the correct expression can be 6x4x4
Answer:
6 x 4 x 4
Step-by-step explanation:
IN order to calculate the total area or the cardboard you just have to make a simple multiplication, the carboard is divided in equal sized squares, 6 equal sizd squares, and each one of them has a 4 inches side, so to calculate the area of the cardboard you just calculate the area of one square and then multiply it by the number of squares.
Area of one square= 4x4
Number of squares=6
Total area of the carboard= 6x4x4

The equation a=640s gives the relationship between s square miles and acres. Pam owns 7.5 square miles of farmland. How many acres does she own
Answer:
4800 acres.
Step-by-step explanation:
We have been given an equation [tex]a=640s[/tex], which gives the relationship between s square miles and acres.
To find the number of acres Pam owns we will substitute [tex]s=7.5[/tex] in our given equation.
[tex]a=640\times 7.5[/tex]
[tex]a=4800[/tex]
Therefore, Pam owns 4800 acres.

Isaiah sketches a model of a skateboard ramp. The model has two surfaces on which to skate, represented by sides AB and AD in the diagram.
The steepest side of the model, AB, measures 4 inches. What is the length of the other skating surface, AD?
A) 2 square root 2
B) 2 square root 3
C) 4 square root 2
D) 4 square root 3
Answer:
(C)
Step-by-step explanation:
It is given that The steepest side of the model, AB, measures 4 inches, thus
From ΔABC, using the trigonometry, we have
[tex]\frac{AC}{AB}=sin45^{\circ}[/tex]
Substituting the given value, we have
⇒[tex]\frac{AC}{4}=sin45^{\circ}[/tex]
⇒[tex]AC=4{\times}\frac{1}{\sqrt{2}}[/tex]
⇒[tex]AC=2\sqrt{2}[/tex]
Now, from ΔACD, we have
[tex]\frac{AC}{AD}=sin30^{\circ}[/tex]
⇒[tex]\frac{2\sqrt{2}}{AD}=\frac{1}{2}[/tex]
⇒[tex]AD=4\sqrt{2}[/tex]
Therefore, the length of AD will be [tex]4\sqrt{2}[/tex]
thus, option C is correct.

What other information do you need to prove ΔABE is congruent to ΔEDA by SSS?
A) A= C
B) ΔEAC is isosceles triangle with base EC
C) E= C
D) EAC is equilateral triangle
Answer:
D) EAC is equilateral triangle
Step-by-step explanation:
Given :
AEC is a triangle in which B∈ AC and D∈EC
Such that,
∠ABE = 90°,
∠ADE = 90°,
Also, BC = CD
We have to prove that :
Δ ABE is congruent to Δ EDA
Proof :
If EAC is an equilateral triangle,
By the property of equilateral triangle,
EA = AC = EC
If AC = EC
⇒ AB + BC = ED + CD
⇒ AB + CD = ED + CD
⇒ AB = ED
Also, AE = AE ( common segment )
Now, if in two right triangles hypotenuse are equal and any corresponding legs are equal,
Then, the other legs must be equal,
That is, BE = DA,
Hence, by SSS postulate of congruence,
Δ ABE ≅ Δ EDA
Therefore, option D is correct.

A science test, which is worth 100 points, consists of 24 questions. Each question is worth either 3 points or 5 points. If x is the number of 3-point questions and y is the number of 5-point questions, the system shown represents this situation.
x + y = 24
3x + 5y = 100
What does the solution of this system indicate about the questions on the test?
A.)The test contains 4 three-point questions and 20 five-point questions.
B.)The test contains 10 three-point questions and 14 five-point questions.
C.)The test contains 14 three-point questions and 10 five-point questions.
D.)The test contains 20 three-point questions and 8 five-point questions.
Consider the equations below.
y = 200 + 350x
y = 3x
When x = 7, which equation has the greater value?
When x=7 , the first equation y = 200 + 350x has the greater value.
To determine which equation has the greater value when x=7, we need to evaluate both equations at x=7 and compare the resulting y values.
For the first equation [tex]\( y = 200 + 350x \):[/tex]
[tex]\[ y = 200 + 350 \times 7 \]\[ y = 200 + 2450 \]\[ y = 2650 \][/tex]
For the second equation y=3x
[tex]\[ y = 3 \times 7 \]\[ y = 21 \][/tex]
Comparing the values, we see that y=2650 for the first equation and y=21 for the second equation.

Calculate the side lengths a and b to two decimal places.

B. a = 16.23 and b = 18.83
C. a = 17.99 and b = 16.23
D. a = 4.81 and b = 5.33
E. a = 5.33 and b = 4.81
Will thank rate five stars and give brainlist anser to first person to answer!
Answer:
A. a = 16.23 and b = 17.99
Step-by-step explanation:
The addition of the three angles of the triangle is equal to 180°. So,
C + 64° + 85° = 180°
C = 180° - 64° - 85°
C = 31°
The law of sine states:
sin(A)/a = sin(B)/b = sin(C)/c
where c is the side opposite to angle C
Taking angles A and C, and sides a and c, we get
sin(A)/a = sin(C)/c
sin(64°)/a = sin(31°)/9.3
sin(64°)*9.3/sin(31°) = a
a = 16.23
Taking angles B and C, and sides b and c, we get
sin(B)/b = sin(C)/c
sin(85°)/b = sin(31°)/9.3
sin(85°)*9.3/sin(31°) = b
b = 17.99
The length of the shadow on flat ground of a man who is 6 feet tall and is standing up straight is 8 feet. The distance between the top of his head and the top of his head in the shadow is feet.
Answer:
The answer is 10 ft.
Step-by-step explanation:
make a triangle 6ft tall, 8ft long (90 degrees to the other line) and draw a line to complete the triangle. This is a type of 3,4,5 triangle, a 6,8,10. The other way to do it is sqrt(6^2+8^2) = sqrt(36+64) = sqrt (100) = 10.
hope this helps!!

Two similar polygons are shown below:
Which transformation was performed on PQRS to form P′Q′R′S′?
A dilation factor of 2
A dilation factor of 4
A dilation factor of 1 over 2
A dilation factor of 1 over 4
Answer: The correct option is (A) A dilation factor of 2.
Step-by-step explanation: We are shown two similar polygons in the figure.
We are to select the transformation that was performed on PQRS to form P'Q'R'S'.
We can see clearly from the figure that two polygons have same shape but different sizes.
So, the only transformation possible from PQRS to P'Q'R'S' is dilation.
To find the dilation factor, we need the lengths of any two corresponding sides of PQRS and P'Q'R'S'.
From the graph, we note that
PQ = 2 units and P'Q' = 4 units.
Therefore, the dilation factor is given by
[tex]D_f\\\\\\=\dfrac{\textup{length of a side of the dilated figure P'Q'R'S'}}{\textup{length of the corresponding side of the original figure PQRS}}\\\\\\=\dfrac{P'Q'}{PQ}\\\\\\=\dfrac{4}{2}\\\\=2.[/tex]
Thus, the required transformation is a dilation with dilation factor of 2.
Option (A) is CORRECT.
