Answer:
x = -3
Step-by-step explanation:
What you do is get x by itself.
1/4(8x - 4) = 5x + 8 <u>Distribute 1/4 to 8x and -4.</u>
2x - 1 = 5x + 8 <u>Subtract 5x on both sides.</u>
-3x -1 = 8 <u>Add -1 to both sides.</u>
-3x = 9 <u>Divide -3 on both sides.</u>
x = -3
Answer:
14
Step-by-step explanation:
Like this ???
I believe it's the 3rd one
Squaring both sides of the given equation: w^2=7w, or w^2-7w=0.
w^2-7w=0 can be factored: w(w-7)=0. Then, w=7 or w=0. Both 0 and 7 are solutions of this equation.
Answer:
(x+3)(x^2+1)
Step-by-step explanation:
If x= -3
X^3+X^2+X+3=-27+27-3+3
=0
Because of that (x+3)(x^2+1)
