Answer:
38. The area is 12x-8
40. The area is 39-13y
Step-by-step explanation:
38. To find the area of a rectangle, you multiply length times width. You have to multiply 4(3x-2) which is 12x-8
40. The area of a triangle is base times height divided by 2. You have to multiply [tex]\frac{13(6-2y)}{2}[/tex] which is [tex]\frac{78-26y}{2}[/tex] to then get 39-13y.
Hope this helped!
