Answer:
y = -2x + 4
Step-by-step explanation:
When given a slope, and y intercept, this means the question is asking us to write the equation in slope-intercept form, which is y = mx + b.
Plug in the values.
y=(-x^2)+12x-20
=(-(3)^2)+12(3)-20
=(-9)+36-20
=16-9=7
y=7

h²=65²-25²=4225-625=3600
h²=x*25
x=h²:25
x=3600:25
