Answer:
9sqrt(2) ft or 12.73 ft
Step-by-step explanation:
A = L^2
sqrt(162) = 9sqrt(2)
The diagonal of a square is equal to the side length.
Youd take two times nine and get 18 so it would be 18.55
True. Polynomial means consisting of several terms. A<span>n expression of more than two algebraic terms, especially the sum of several terms that contain different powers of the same variables.
For example:
f(x) = x3 + 2x 1/2
Since there are two parts to this equation, it is polynomial.

<span>5 = 15
---------
8 = x
cross multiply
5x =120
5x÷5 = 120÷5
x = 24
Check
5/8 = 15/24
.625 = .625

20+4x=76 subtract 20 from both sides
4x=56 divide both sides by 4
x=14
So he was driving at 55+14=69 mph
