Answer:
a)x²y²+2xy²z+y²z²-2x²y²z²
b) -8
Step-by-step explanation:
foil the squared to get:x²y²+2xy²z+y²z²
and then plug in the numbers and chug along
hope this helps
Function : $8000 = $1200 + $700x
They will raise $700 per month for x months -> $700x is the amount of money they raise per month.
Since $8000 is the sum in the function, it is the goal.
Therefore, $1200 in this case means they started with $1200.
Use the equation of -b/2a, so if you have a line you can just plug in the numbers.
I would say origin, but it's a hard choice.
D.y = -3/5x - 2
