A rectangle has a height of 3 and a width of 2x^2+3x-5 express the area of the rectangle

6x²+ 9x- 15

Step-by-step explanation:

To find the area of a rectangle multiply length and width.

3(2x²+ 3x-5)

Use the distributive property to solve.

3(2x²)= 6x²

3(3x)= 9x

3(-5)= -15

The area would be

6x²+ 9x- 15

x+y = 29, 5x + 2y = 100
