<span>y=3(x-40)^2-22
y = 3(x^2 - 80x + 1600) - 22
y = 3x^2 - 240x + 4800 - 22
y = 3x^2 - 240x + 4778
answer
</span><span> standard form of the equation
</span>y = 3x^2 - 240x + 4778
Answer:
5 6/12 or 5 1/2
Step-by-step explanation:
Answer:
x-y=2
I don't get why they are asking you what is 2-5. That seems super basic compared to the other question it is with. Since 5-2=3, then 2-5 or -5+2=-3.
Step-by-step explanation:
We are going to use identity x^2-y^2=(x-y)(x+y)
x^2-y^2=10
(x-y)(x+y)=10
(x-y)(5)=10
Since (2)(5)=10, this implies x-y=2.
Answer:
x=9
Step-by-step explanation:
(9-7) = 2
9 times 2 = 18 square feet
