i need some help lol so um new to learning on algebra and my teach not doing to good on explaining. so here is my problem to solve If a x b = 2a - 3b + ab, then 3 x 5 + 5 x 3 is equal to?

3 x 5 + 5 x 3 would be equal to 30  

Step-by-step explanation:

3 * 5 + 5 * 3 = (2 * 3 - 3 * 5 + 3 * 5) + ( 2 * 5 - 3 * 3 + 5 * 3)

= (6 + 10 - 9 + 15) = 22.

trapezoid

step-by-step explanation:

first i plotted all my points on a grid graph

i made sure all of them were in the correct quadrant
