Answer:

x(2x + 3) + (x - 3) (x - 4) = 3x²- 4x + 12

Step-by-step explanation:

<em>Expand:</em>

x(2x + 3): 2x² + 3x

2x² + 3x + (x - 3) (x - 4)

<em>Expand</em>:

(x - 3) (x - 4):  x²- 7x + 12

2x² + 3x + x²- 7x + 12

<em>Simplify:</em>

2x² + 3x + x² - 7x + 12:  3x² - 4x + 12

= 3x² - 4x +12

15. Gwen had a painting that had a length of 5 feet and a width of 3.5 feet.
victus00 [196]

Answer:

D. 15 by 10.5

Step-by-step explanation:

If the original painting has dimensions of 5 by 3.5, and has a scale factor of 1, then if we are trying to find the dimensions of the same thing but with a scale factor of 3, then we need to multiply the dimensions by 3.

5*3 = 15

3.5*3 = 10.5

The new dimensions are 15 by 10.5.

Hope this helps. Have a nice day.
