<h3>Answer: Choice C. v^4w^2+15v^2w^3+2</h3>
================================================
Work Shown:
(9v^4+2)+v^2(v^2w^2+2w^3-2v^2)-(-13v^2w^3+7v^4)
9v^4+2+v^2*v^2w^2+v^2*2w^3+v^2*(-2v^2)-(-13v^2w^3)-(7v^4)
9v^4+2+v^4w^2+2v^2w^3-2v^4+13v^2w^3-7v^4
(9v^4-7v^4-2v^4)+v^4w^2+(2v^2w^3+13v^2w^3)+2
(0v^4)+v^4w^2+(15v^2w^3)+2
v^4w^2+15v^2w^3+2

Answer:
Step-by-step explanation:
According to the Order of Operations [GEMS\BOMDAS\PEMDAS etc.], Subtraction & Addition are evaluated after Division & Multiplication:
I am joyous to assist you anytime.
8x +7y = 39 multiply everything by 2
2(8x +7y = 39)
16x +14y = 78
+4x - 14y= -68
-------------------------
20x = 10
20x /20 = 10/20
x = 1/2
Plug x into first formula
8 x + 7y =39
8(1/2) 7y=39
4+ 7y =39
4-4+7y =39-4
7y =35
7y/7 = 35/7
y = 5
(1/2, 5)
