Yep! The answer is 9
When using the Pythagorean theroem, you use a^2+b^2=c^2
Because c represents the hypotenuse, c=15
and a=12
12^2+b^2=15^2
144+b^2=225
b^2=81
b=9

Answer:
He walked for 70 minutes
Step-by-step explanation:
Find the unit rate by dividing 20/4 to get 5. Then you multiply 14x5 and get 70.
To calculate f(x) + g(x)
=3/5x + (-3x/2)
=3/5x - 3x/2
=2(3)/2(5x)-(5x)(3x)/(5x)(2)
=(6/10x-15x^2)/10x
=(15x^2-6)/-10x
Thus the answer is D
