32w^3 + 16x^2 - 8

Step-by-step explanation:

Perimeter = 2L + 2W

L = 9W^3 + 8W^2, W = 7w^3-4

2(9w^3 + 8w^2) + 2(7w^3 - 4)

= 18w^3 + 16w^2 + 14w^3 - 8

Combine like terms

32w^3 + 16w^2 - 8

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
