Step-by-step explanation: Edge 2021
A cube has side length x. One side of the cube is increased by 4 inches, and another side is doubled. The volume of the new rectangular prism is 450 cubic inches. The equation 2x3 + 8x2 = 450 can be used to find x. What was the side length of the original cube? Use a graphing calculator and a system of equations to find the answer.
4 inches
5 inches
9 inches
10 inches
The length of the side of the original cube in the given scenario is 5 inches.
A cube is a three-dimensional figure with equal sides.
Given that
The length of the edge of a cube = x
Also, one of the sides is increased by 4 inches, and another side is doubled,
so, now the new dimensions are x, x+4, 2x, and the shape is a rectangular prism.
The area of the rectangular prism = 450 sq. inches
base × height × length = 450 sq. inches
x × (x + 4) × 2x = 450
2x³ + 8x² = 450
2x³ + 8x² - 450 = 0
x³ + 4x² - 225 = 0
Substitute x=5 to see that it is a root of the equation,
5³ + 4(5)² - 225 = 125 + 100 - 225 = 0
So, x - 5 is a factor of the equation,
Now,
x³ + 4x² - 225 = (x−5)(x² + 9x + 45) = 0
The roots of the quadratic equation are imaginary as
D = 9² - 4 × 1 × 45 = 81 - 180 = -99
The discriminant is negative, therefore, the roots are not real.
So, the length of the side of the original cube is 5 inches.

Which of the points shown below are on the line given by the equation y = x - 1? Check all that apply.
A. Point A: (1, -2)
B. Point B: (2, 1)
C. Point C: (4, 3)
D. Point D: (-3, -4)
Final answer:
To find points on the line y = x - 1, substitute the x and y values of each point into the equation. Points B, C, and D satisfy the equation.
Explanation:
The equation given is y = x - 1. To determine which points lie on this line, you need to substitute the x and y values of each point into the equation and see if the equation holds true.
Point A: (1, -2) - Substitute x = 1, y = -2 into y = x - 1. -2 = 1 - 1 is false.Point B: (2, 1) - Substitute x = 2, y = 1 into y = x - 1. 1 = 2 - 1 is true.Point C: (4, 3) - Substitute x = 4, y = 3 into y = x - 1. 3 = 4 - 1 is true.Point D: (-3, -4) - Substitute x = -3, y = -4 into y = x - 1. -4 = -3 - 1 is true.Therefore, Points B, C, and D lie on the line represented by the equation y = x - 1.

Quadrilateral MNOP is a rhombus. Find the measure of angle MRN.
a. 90
b. 45
c. 85
d. 60
Without further information or a diagram indicating the position of point R in the rhombus MNOP, we cannot accurately determine the measure of angle MRN. If R is at the intersection of the diagonals, angle MRN would be 90 degrees.
Explanation:The student asks to find the measure of angle MRN in a rhombus named MNOP. Unfortunately, the information provided is insufficient to determine the measure of angle MRN directly. However, one property of a rhombus is that all sides are of equal length and opposite angles are equal. Additionally, the diagonals of a rhombus are perpendicular bisectors of each other and bisect the angles of the rhombus. Without a specific diagram or more information about the location of point R in relation to the rhombus, it's impossible to give an exact answer. If R is located at the center where the diagonals intersect, then angle MRN would be 90 degrees because the diagonals of a rhombus bisect each other at right angles. If R is not at the center, then we cannot determine the angle without additional information.
"In ABC, mBAC = 5x + 8, mABC = 6x + 22, and mBCA = 3x 25.
A.Find the value of x.
B.Find the measure of 3. Show your work."
Actually, the answer is 12.5
5x+8+6x+22+3x+25= 180
(5x+6x+3x)+(8+22-25)= 180
14x+5=180
14x+(5-5)=180-5
14x=175
14x/14=175/14
X=12.5
Double check:
(5*12.5)+8=70.5
(6*12.5)+22= 97
(3*12.5)-25=12.5
70.5+97+12.5=180 degrees.
So, x=12.5

The lengths of the sides of a triangle are 3x, 5x – 12, and x + 20. Find the value of x so that the triangle is isosceles. ...?
Final answer:
To find the value of x for the triangle to be isosceles, we set the lengths of any two sides equal to each other and solve for x. After testing different cases, we find that x equals 10 satisfies the condition for the triangle to be isosceles.
Explanation:
For a triangle to be isosceles, at least two sides must have equal length. We're given the side lengths as 3x, 5x - 12, and x + 20. We have two cases to consider to find the value of x for the triangle to be isosceles:
Case 1: 3x = 5x - 12
Case 2: 3x = x + 20 or 5x - 12 = x + 20
To solve for x in case 1, we equate the two expressions and solve as follows:
3x = 5x - 12
2x = 12
x = 6
However, if we substitute x = 6 into the third side (x + 20), we get a length of 26, which does not equal either of the first two sides. Therefore, x = 6 does not satisfy the condition for an isosceles triangle.
For case 2, we consider 3x = x + 20:
3x = x + 20
2x = 20
x = 10
By substituting x = 10 into 5x - 12, we get 50 - 12 = 38. We can see that two sides of the triangle are 30 and 30 (since 3x equals 3(10)), confirming that the triangle is isosceles with x equal to 10.

Janet’s car insurance payment decreases by $30 each year. which expressions represent the total change in her payment, in dollars, after 44 years?
The total change in Janet's car insurance payment after 44 years is $1320.
Explanation:To find the total change in Janet's car insurance payment after 44 years, we can use the formula:
Total change = decrease per year × number of years
In this case, the decrease per year is $30 and the number of years is 44. So the expression representing the total change in her payment would be:
Total change = $30 × 44 = $1320
Therefore, Janet's car insurance payment will decrease by $1320 after 44 years.
