Very simple
? – (20 – 4x – 5x2) = 20 – 7x2, so ? = 20 – 7x2 <span>+ (20 – 4x – 5x2)
</span>? = 20 – 7x2 <span>+ (20 – 4x – 5x2)=20-7x²+20-4x-5x²=40-12x²-4x
</span>the answer is <span>C. 40-4x-12x^2</span>

Answer:
y=3 x=4
Step-by-step explanation:
4x - 2y = 10
<u>4x + y = 19</u>
-3y=-9
the 4x canceled out.
y=3
plug in y into one of the equations
4x + 3 = 19
4x=16
x=4
Hope this helps!
If not, I am sorry.
