Question

A rectangle has a height of 3and a width 2x^2+3-5 Express the entire angle
​

Answer 1

Step-by-step explanation:

The area of a rectangle is height × width

Here the height is 3

the width is 2x^2 + 3x - 5

so the area is 3 ×(2x^2 + 3x - 5)

using the distributive property (a(b+c) = ab + ac)

the area is 3×2x^2 + 3×3x - 3×5

6x^2 + 9x - 15
