1. Reduce <span>3x2-6x-240 to x^2 - 2x - 80
2. Use " ^ " to indicate exponentiation
3. Factor </span>x^2 - 2x - 80 using completing the square:
x^2 - 2x + 1^2 - 1^2 - 80
(x+1)^2 - 1 - 80
(x+1)^2 - 81
(x+1)^2 - 9^2 = (x+1-9)(x+1 +9), or (x-8)(x+10)
Final answer, with all factors shown: 3(x-8)(x+10)
Answer:
For #1, 8.9.
Step-by-step explanation:
I can attempt to answer it, but I can't promise anything.
Alright, so, the equation for this should be A²+B²=C²
C is usually the longer side, which for you is the side that is missing.
Let's try the first one. If what I see is right, the 2 sides are 4 and 8. A is 8 and B is 4.
That means that the equation would be 8²+4²=C²
That would be 64+16=80
The equation is now 80= c²
The opposite of "to the power of 2" is a square root. So, now you're going to find the square root of 80, which is 8.9 to the nearest tenth.
So, for the first question, the answer should be 8.9
I hope this helps you solve the rest.

=5(3)-1
=15-1
=14
Therefore, the answer is 14.
