Answer:
x² - 16
Step-by-step explanation:
Use the FOIL method here where
F = first
O = outer
I = inner
L = last
F = x * x = x²
O = -4 * x = -4x
I = 4 * x = 4x
L = -4 * 4 = -16
Combine the terms to get x² - 16.
Answer:
if the question is 2xy²(23x²y³) then the answer is 46x³y^5
Step-by-step explanation:
-2/5n=-30n
multiply both sides by -1 sinc I don' like negatives
2/5n=30n
multipl yboth sides by 5/2
1n=150/2n
n=75n
this is obviously false, the only number that would work is 0 since 0 =0 times 75
n=0
Answer: 5/3
One of the side lengths goes from 3 to 5. So, the scale factor is 5/3.
Hope that helped!
