W=20 feet = 55% thus 20/55*100= L=36.36 Feet Fromula A=w*l
A=727.2 Feet²
To prove the sum is 4z you can say I put an imaginary 1 in front of z because we know a variable by itself always has a one.
Add 300 and then will still be confused
The Pythagorean Theorem states that a^2+b^2=c^2
We already have:
A^2+6^2=117
All we need to do is find the missing A by subtract b from c.
117-36=81
Now the square root of 81, 9.
So, x is 9 cm.
Answer:
The answer would be A.
