X × x = x^2
x × -3 = -3x
3 × x = 3x
3 × -3 = -9
x^2 + 3x - 3x - 9
So I would agree with C because the -3x and the 3x cancel each other out. I hope this helps!
Yes it’s correct my sister had something similar to that :)
Answer:
41.882
Step-by-step explanation:
43 x 2.6% is 1.118, and when you subtract that from 43, you get 41.882.
A+5 = 1 side, so the perimeter is 3(a+5) or P = 3a+15
