If you're solving for a, you would add 32 to both sides
2a=32
then you would divide by 2
a=16
Slope intercept form is

, where 'm' is the slope and 'b' is the y-intercept.

Subtract 6x to both sides:

Divide 5 to both sides:
Answer: 8 inches
Explanation:
a^2 + b^2 = c^2
6^2 + b^2 = 10^2
36 + b^2 = 100
b^2 = 64
(Have to find the square root of 64)
= 8 inches
Answer: 56
Step-by-step explanation: Divide 42 by 3 and then multiply by 4
