Answer:

29.7

Step-by-step explanation:

y = 2.7x + 2.7

y = 2.7(1) + 2.7 = 5.4

y = 2.7(2) + 2.7 = 5.4 + 2.7 = 8.1

y = 2.7(3) + 2.7 = 8.1 + 2.7 = 10.8

y = 2.7(4) + 2.7 = 10.8 + 2.7 = 13.5

y = 2.7(10) + 2.7 = 27 + 2.7 = 29.7

Natasha_Volkova [10]

Answer:

p=18x+4

a=20x^2+17x-63

a=1350

Step-by-step explanation:

Given:

l=5x-7

w=4x+9

Required:

Area of the rectangle=?

Perimeter of the rectangle=?

If x = 9 inches what is the area of the shape=?

Formula:

a=l*w

p=2(l+w)

Solution:

p=2(l+w)

p=2(5x-7)+2(4x+9)

p=10x-14+8x+18

p=10x+8x+18-14

p=18x+4

a=l*w

a=(5x-7)(4x+9)

a=20x^2+45x-28x-63

a=20x^2+17x-63

Area of the shape if x=9in

a=20x^2+17x-63

a=20(81)+17(9)-63

a=1620+153-63

a=1413-63

a=1350
