Answer:
The answer is C
Step-by-step explanation:
If y is equal to 2 then you can find x by putting 2 for y so you will have:
2x + 8(2) = 20
2x + 16 = 20
2x = 20 - 16
2x = 4
x = 4/2
x=2 :)))
i hope this is helpful
have a nice day
This question is ambiguous because we don’t know if the two numbers are -4x^4 and -8x^3 or (-4x)^4 and (-8x)^3. In the first case 4x^3 is present in both and nothing else is. In the second case (4x)^3 is the largest common factor.
Answer:
25
- 30xy + 20xz + 9
- 12yz + 4
Step-by-step explanation:
We multiply it out.
(5x - 3y + 2z) * (5x - 3y + 2z)
5x*5x + 5x*-3y + 5x*2z - 3y*5x - 3y*-3y -3y*2z + 2z*5x +2z * -3y +2z *2z
25 - 15xy + 10xz - 15xy + 9 - 6yz + 10xz - 6yz + 4
Add like terms
25 - 15xy - 15xy + 10xz + 10xz + 9 - 6yz - 6yz + 4
25 - 30xy + 20xz + 9 - 12yz + 4
