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:
x is 6 because
y is 30
p is 120
Step-by-step explanation:
60 degrees and 10x are the same and 6×10 = 60
(4y) and 60 degrees must equal 180 so y has to be 30
(4y) and p are the same
Answer: First one is B second one just make it
Step-by-step explanation:
These numbers are "a" and "b".
Sum is 64, so
a+b=64
Difference is 42 so
a-b=42
So you've got:

When a+b=64 and a=53 you've got:
53+b=64
b=11
So these numbers is 53 and 11.
