Q = p(r + s)
Use the distributive property
Q = pr + ps
Q = p x r + p x s
Q = p x p + r x s
Q = p^2 + rs
Subtract rs from both sides
Q - rs = p^2
Square root both sides
sqrt Q - rs = p
X= -2 or X= 3 either one works.
Answer:
7.5
Step-by-step explanation:
1 foot is 12 inches so I just divided.
You can solve this by algebraically as well as graphically. When I tried both ways I got:
solution is x= -2<span />
