thx anonymous 100%
5 is right. I don't know about 4.
The others are wrong.
Unfortunately #4 is wrong too.
Looks like some major review and studying lies ahead of you.
1. (2x)(10x)
C; 20x^2
2. -3m(m + 8)
B; -3m^2 - 24m
3. 4d(2d - 9)
D; 8d^2 - 36d
4. (7x + 1)8x or Find the area of the rectangle
B; 56x^2 + 8x
5. 5b(6b - 10)
D; 30b^2 - 50b
Looks like you got most of the answers correct! Let's go through them one by one to make sure:
1. (2x)(10x) = 20x². So the correct answer is C: 20x².
2. -3m(m+8) = -3m² - 24m. So the correct answer is B: -3m² - 24m.
3. 4d(2d-9) = 8d² - 36d. So the correct answer is D: 8d² - 36d.
4. The area of a rectangle is found by multiplying its length and width. In this case, the length is 7x+1 and the width is 8x. So the area is (7x+1)(8x) = 56x² + 8x. Therefore, the correct answer is B: 56x² + 8x.
5. 5b(6b-10) = 30b² - 50b. So the correct answer is D: 30b² - 50b.
Great job on most of the answers! If you have any more questions, feel free to ask.
