A double negative makes a positive
-9 - (-4) = -9 + 4 = -5
B = -12
x^2 + 12x + 36
(x+6)(x+6)
Answer:
x=1
Step-by-step explanation:
We distribute the negative 5 to x minus three to get 8x-5x+15=18. Then, we cancel out the 15 by subtracting it from both sides. This leaves us with 8x-5x=3. When we subtract, we get 3x=3, and when we divide both sides by 3, we get x=1. Hope this helps :)
Answer:
D
Step-by-step explanation:
The PERIMETER will be 4/5 of the original if you reduce the sides by 4/5
area will be reduced by 4/5 * 4/5 = 16/25 of original
