Therefore, s would be the square root 729:
Your answer is 27 ft.
To solve this problem, we should set up an equation, letting the unknown number be represented by the variable x.
2/3x = 20
To solve this equation, we just have to divide both sides of it by 2/3, because we are trying to get the variable alone on the left side of the equation.
x = 30
Therefore, the number is 30.
X > -8

MN is the mid-line of a trapezoid HJLK.<span>
The length of the mid-line of a trapezoid is half of the sum of the lengths of its bases </span>⇒

(KL + HJ)/2 = MN
(KL + 45)/2 = 28
KL + 45 = 28 * 2
KL + 45 = 56
KL = 56 - 45
KL = 11
