B, because 12 inches equals one foot so it's one foot a minute. In an hour it would walk 60 feet as to A would only walk 52
<span>All the angles of a triangle add up to 180 degrees.
Since two of the angles are the same, we can write:
2A+B=180
Where 2A accounts for the two angles that are the same.
We are given the relation:
B=A+30
We can plug this into our first equation:
2A+A+30=180
</span><span>
Combine like terms and move the 30 to the other side:
3A=150
Divide both sides by 3:
A=50
We can solve for B by plugging A back into our relation:
B=50+30
B=80
To check: 80+50+50 so we are correct.</span>

Correct Answers:
0.25x²+0.8x-8=0
5x²+7x=15
Reasons: 0.25x²+0.8x-8=0 is already in standard quadratic form, so you can just use the numbers in the quadratic formula.
5x²+7x=15 is also in standard form; all you have to do is change it from the original equation to proper standard form by moving the 15 to the other side. Thus, that equation is changed to 5x²+7x-15=0. I hope this helps you. ☺
