To solve this, use the ‘completing the square’ strategy.
Leave a space to make the first two values a perfect square.
y=(x^2-2x___)-3
Divide -2 by 2 and square that number to put in the blank. Then subtract that number from outside.
y=(x^2-2x+1)-3-1
Simplify!
y=(x-1)^2-4
It is in vertex form now ;)

Well the best answer i could get was for 22min bike 11mph
and for 38min bike 15mph
and that will put him at 600.5 calories every hour
Answer:
Step-by-step explanation:
The total of all 3 angles in every triangle equals 180 degrees. An isosceles triangle has two side lengths equal and two angle degrees equal.
So you either have two angles with each having 70 degrees and the third angle is 40 degrees,
70 + 70 + 40=180
OR
One angle of 70 degrees and two angles that are 55 degrees each.
70 + 55 +55 =180
