It would be a translation and a dilation. I'm sorry if I'm wrong and i can't explain how i know
Answer:
x^2 + x -12
Step-by-step explanation:
I am going to expand and simplify because you haven't mentioned what to do:
(x-3)(x+4)
x^2 +4x -3x- 12
x^2 +x-12
Subtract both widths of the pool from the perimeter.
124-40= 84yd
Divide the two lengths of the pool by two to get the measurement of one length.
84/2= 42yd
Colton swam 42 yards.
that's the solution ^
the answer is: 847.98 m^2
