Answer:
21. 3x^2 +7x
22. 6x^3 +3x
Step-by-step explanation:
21. The perimeter is the sum of the side lengths.
P = (x^2 +3x +1) +(4x -1) +(2x^2)
P = x^2(1 +2) +x(3 +4) +(1 -1) . . . . combine like terms
P = 3x^2 +7x

22. The area is the product of the dimensions.
A = (3x)(2x^2 +1)
A = 6x^3 +3x . . . . . use the distributive property
In y = mx + b form, the slope is represented by m and the y intercept is represented by b
y = mx + b
y = -7x + 2

Answer:
z = 19
Step-by-step explanation:
Given
2(4z - 9 - 7) = 166 - 46 ← simplify both sides
2(4z - 16) = 120 ← distribute parenthesis on left side
8z - 32 = 120 ( add 32 to both sides )
8z = 152 ( divide both sides by 8 )
z = 19
