Assuming you need to find the solution, it's x=3 and y=6
I used elimination
What’s something goes up but never comes down?
Answer:
x + 2
Step-by-step explanation:
If we know one of the factors, we should be able to use long division.
We can divide the trinomial by the binomial and find the other factor.
<u>x + 2</u><u> </u>
x² + 4x + 3)x³ + 6x² + 11x + 6
<u>x³ + 4x² + 3x</u>
2x² + 8x + 6
<u>2x² + 8x + 6</u>
0
Thus,

Solution:
Given:

when a = 4, substitute for a in the expression;

Therefore, if (a = 4), then

Hence, the answer is 16.
