Answer:
X = 10 or scale factor is 2.5
Step-by-step explanation:
first look at the scale factor going from 4 to 10, to get from 4 to 10 you would need to multiply 4 by 2.5. Since this problem doesnt give us the smaller scale factor first we need to divide 25 by 2.5 which equals 10.
12
72/6 = 12
Or 72= h*6
Be sure to mark me brainliest!
i think n = 4
3(n+7) = 33
3n+21 = 33
3n = 12
n = 4
