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
Answer:
Four consecutive integers are represented by: x, x+1, x+2, x+3 Their sum is 4x+6 4x+6 = 90
