Hello!
1. -4x2 + 8x + 32
-4(x2 - 2x - 8)
-4(x2 + 2x - 4x - 8)
-4(x(x + 2) - 4(x + 2))
-4(x + 2)(x - 4)
Answer A.
2. 2x2 + 16x + 30
2(x2 + 8x + 15)
2(x2 + 5x + 3x + 15)
2(x(x + 5) + 3(x + 5))
2(x + 5)(x + 3)
Answer C.
Answer: y=2
X=3
5.2+10.3=10+30=40
Step-by-step explanation:
The equation has no solution.
<h3>How to solve the equation?</h3>
The equation given is illustrated as:
3x-2y=3 .... i
6x-4y=1 ..... ii
Multiply equation i by 6
Multiply equation ii by 3
18x - 12y = 18
18x - 12y = 3
Subtract the equations.
This will give 0. Therefore, the equations gas no solution.

Do the formula length times width times height.
Then, round like you normally would!
And for the second one, just multiply 2.5 x 6!
You will add the two numbers together and add the t as well to make 33t
