Answer:

[tex]3x^4-7x^3+x^2+2x+11[/tex]

Step-by-step explanation:

[tex]3x^2(x^2 - 4x - 2) + (5x^3 + 7x^2 + 2x + 11)[/tex]

First, I will expand the expression [tex]3x^2(x^2 - 4x - 2)[/tex]

[tex]3x^2(x^2 - 4x - 2) \\3x^4-12x^3-6x^2[/tex]

So, we got

[tex]3x^4-12x^3-6x^2+ 5x^3 + 7x^2 + 2x + 11[/tex]

Adding similar elements, we get:

[tex]3x^4-7x^3+x^2+2x+11[/tex]

Answer:

The set (39, 80, 89) can be used to make a right triangle. Thus, option D is correct.

Explanation:

We know that right-angle triangles obey the Pythagoras theorem, i.e.,

a² + b² = c²

Let's check for each set:

(39, 41, 45): 39² + 41² ≠ 45²

(39, 49, 59): 39² + 49² ≠ 59²

(39, 69, 99): 39² + 69² ≠ 99²

(39, 80, 89): 39² + 80² = 89²

Answer: The correct answer is C.35.

Step-by-step explanation:

70÷2=35

The value of the measure of XBA is,

⇒ 35 degree

An angle is a combination of two rays (half-lines) with a common endpoint. The latter is known as the vertex of the angle and the rays as the sides, sometimes as the legs and sometimes the arms of the angle.

We have to given that;

Here, ray BA bisects XBY which measures 70 degrees

Hence, The value of the measure of XBA is half of the measure of XBY.

So, We get;

the measure of XBA is,

⇒ 70 / 2

⇒ 35 degree

Thus, The value of the measure of XBA is,

⇒ 35 degree

Answer:

Option D, 7, is the right answer.

Step-by-step explanation:

It is given that 28 slips of papers are numbered through 1 to 28.

Accordingly, there are 28 numbers.

For a fair decision, the number of slips with each one must be the same.

Therefore, the decision will only be fair if the number of people in the group is a factor of 28.

The factors of 28 are -  1, 2, 4, 7, 14 and 28.

In this way, 7 is the only factor of 28 among the given options.

Hence, the answer will be 7.

Answer:

-4 degrees

Step-by-step explanation:

Starting at 2 degrees, you need to subract 6 since 200 km= 6 degrees and it decreases.

The temperature after 200 km of the polar bear's journey is -4° C.

A word problem is a verbal description of a problem situation. It consists of  few sentences describing a 'real-life' scenario where a problem needs to be solved by way of a mathematical calculation.

For the given situation,

The daily average temperature decreases 3°C for every 100 km traveled

At the start of the bear's journey, the temperature is 2°C

The total distance traveled by the polar bear = 200 km

For 200 km, [tex](3+3)[/tex] totally 6° C should get decreased.

⇒ [tex](2-6)[/tex]

⇒ [tex]-4[/tex]

Hence we can conclude that the temperature after 200 km of the polar bear's journey is -4° C.

Coordinates are written in (x,y) form

(x,y)=(7,3)(Given)

Answer:

A

Step-by-step explanation:

7 units away from the origin in the direction of the x-axis

So it can be (7, ?) or (-7, ?)

3 units away in the direction of the y-axis

So it can be (7, 3) or (-7, -3) or other things

Divide each side by 4

4/4 |x+3|>8/4

|x+3|>2

Absolute value inequalities have 2 solutions, one positive and one negative

Remember to flip the inequality when finding the negative solution

Answer:

39 ft²

Step-by-step explanation:

Area of a triangle = 1/2bh

Let:

base = b = 4 ft

height = h = 3 ft

Solve for the area of the triangle:

A = 1/2(4)(3)

A = 2 * 3

A = 6 ft²

Area of a rectangle = bh

Let:

base = b = 9 ft

height = h = 5 ft

Solve for the area of the rectangle:

A = (9)(5)

A = 9 * 5

A = 45 ft²

Subtract the area of the triangle from the area of the rectangle:

45 - 6 = 39 ft²

39 ft² is your answer.

y = 8

Step-by-step explanation:

Since it gives you x, you need to plug in the number given for it into the equation:

y = 3x - 1

y = 3(3) - 1

y = 9 - 1

y = 8

So now you have, x = 3 and y = 8

percentage, a relative value indicating hundredth parts of any quantity.

We can use the formula for compound interest to solve this problem:

[tex]A = P(1 + r/n)^(^n^t^)[/tex]

where A is the total amount,

P is the principal

r is the annual interest rate,

n is the number of times the interest is compounded per year, and

t is the number of years.

P = $50,000, r = 0.06, n = 12 and t = 10.

Substituting these values into the formula, we get:

A = 50000(1 + 0.06/12)¹²⁰

A = 50000(1.005)¹²⁰

A=$90970

Therefore, the investing group will have $90970 at the end of 10 years.

The statements that are true about the considered figure (given below) are given by: Option C: It is a triangular prism, Option F: It has 5 faces

Take a traingle. This is a base. Now take 3 triangles such that each of them are connected to one-one side of the first traingle and when they're taken together, they form a closed object, called as a triangular pyramid

Take a rectangle. This is the base. Now take 4 triangles such that each of them are connected to one-one side of the base rectangle and when they're taken together, they form a closed object. That shape is called rectangular pyramid.

Connect three rectangles edge to edge. Now close their triangular mouths from both ends. That shape is called a triangular prism.

Faces are planar mathematical objects. Like a triangle, a rectangle etc. Edges are those line segments, which are on the edge of the faces (of some object considered).

Vertices are points of intersections of different edges.

The missing figure is attached below.

It consists of 3 rectangles joined edge to edge, and have two triangular ends in the shape they form, thus, making a triangular prism.
