Answer:

$128.40

Step-by-step explanation:

Find the total cost of the pizza before tax.

15 × 8 = 120

Set up a proportion to find the tax.
7/100 = x/120

Cross multiply

840 = 100x

Divide both sides by 100

Tax = $8.40

$120 + $8.40 = $128.40


I hope this helped and please mark me as brainliest!

Given:

Length of rectangle = 2x-9

Width of rectangle = x+5

Required:

Area of rectangle

Formula:

Area\,\,of\,\,rectangle=Length*Width

Putting values of length and width:

Area\,\,of\,\,rectangle=Length*Width\\Area\,\,of\,\,rectangle=(2x-9)(x+5)\\Area\,\,of\,\,rectangle=2x(x+5)-9(x+5)\\Area\,\,of\,\,rectangle=2x^2+10x-9x-45\\Area\,\,of\,\,rectangle=2x^2+x-45

So, Area of rectangle is 2x^2+x-45
