Answer: 2) 4x - 8 - 8y
Step-by-step explanation:
if xy=4
then y(x-4)(x+2) use foil method with parenthisies to get
y(x²+2x-4x-8) foil again
x²y+2xy-4xy-8y plug 4 in for xy
x²y+2(4)-4(4)-8y solve what u can
x²y+8-16-8y= x²y-8-8y
for x²y if you take out the exponent you have an xy and an x so when u plug in 4 you get 4x ending up with a solution of
4x-8-8y
Hope that helped
Your answer is B. I can explain, but I know some people just need it fast. lol
Answer:
9π miles²
