25x + (57+x) = 45x
26x + 57 = 45x
57 = 19x
x = 3
Answer:
(b) {-8, 2}
Step-by-step explanation:
The given equation
x³ +6x -16 = 0
cannot be factored in integers. It has one irrational real root near x=1.759, and two complex roots.
__
Perhaps you want to factor ...
x² +6x -16 = 0
(x +8)(x -2) = 0
This has solutions x = -8 and x = 2 that make the factors be zero.

<em>Additional comment</em>
"Cubed" refers to an exponent of 3.
If you mean is it equally or not
The answer will be false
Because 2 multiply by 8 equal 16
2x+16 not equal to 2x-8
Answer:
It is A.
