A) Height -7 = base
B) .5 * height * base = 60
Substituting A into B
B) .5 * height * (height -7) = 60
B) .5*height^2 -3.5*height = 60
B) .5*height^2 -3.5*height -60 = 0
Using the quadratic formula:
Height = 15
Subtracting 7 gives us the base length
Base = 8
**************************************************************
Double-Check
.5 * 15 * 8 = 60

Hi there!

We can calculate slope using the following formula:

Plug in the corresponding points:

Simplify:

Answer:
[See Below]
Step-by-step explanation:
✦ Divide by -2 on each side:
✧ -2 / -2 = Cancels Out
✧ -6 / -2 = 3
So x would be 3, -3.
- |x| Just means absolute value. Which in short just means if it's negative it becomes positive.
