Answer:
A. 48
Step-by-step explanation:
Substitute the first equation into the second equation. You will get:
4x - (2x - 5) = 7
Distribute the negative sign into the parenthesis:
4x - 2x + 5 = 7
Simplify
2x + 5 = 7
Subtract 5 on both sides
2x = 2
x = 1
Now, substitute x = 1 into the first equation:
y = 2(1) - 5
y = 2 - 5
y = -3
The solution to the system of equations is (1, -3).
I think the answer is 32m2

Answer:
(u + 1)(u - 1)(u² + 8)
Step-by-step explanation:
<u>Here is the steps:</u>
- u⁴ + 7u² - 8 =
- u⁴- u² + 8u²-8 =
- u²(u² - 1) + 8(u² -1) =
- (u² - 1) (u² +8) =
- (u + 1)(u - 1)(u² + 8)
