Well what two numbers multiply to get -8 and add to get -2?
Well, to get -8, we either have (-1,8),(-2,4),(-4,2),(-8,1)
8-1=7
-2+4=2
2-4=-2
1-8=-7
Thus it should be (-4,2),
This means we should get (X-4)(X+2)
Answer:
you simplify it? I dont really know. :/

Answer:
64
Step-by-step explanation:
4^3 is just 4*4*4
so 4*4=16
and 16*4=64

Answer:
7x³y² - 3x²y² + xy - 5
Step-by-step explanation:
Add like terms.
5x³y² + 2x³y² = 7x³y²
-3x²y² = -3x²y²
-3xy + 4xy = xy
2 - 7 = -5
Put them all together.
7x³y² - 3x²y² + xy - 5
the 2 angles are congruent so...
x+40=3x set the 2 equations equal to each other
40=2x subtract x from both sides
20=x divide by 2
x=20 is the final answer
Have a blessed day!
