Answer:
x=17
Step-by-step explanation:
8x+20=11x-31
We simplify the equation to the form, which is simple to understand
8x+20=11x-31
We move all terms containing x to the left and all other terms to the right.
+8x-11x=-31-20
We simplify left and right side of the equation.
-3x=-51
We divide both sides of the equation by -3 to get x.
x=17
Hi there!


We can use "Completing the Square" to solve:
f(x) = x² - x + 2
Group the variables. The "x" term's coefficient will be divided by two and squared for the third part of the trinomial. Remember to subtract by the third term:
f(x) = x² - x + (1/2)² + 2 - (1/2)²
Group:
f(x) = (x - 1/2)² + 2 - 1/4
Rewrite:
f(x) = (x - 1/2)² - 7/4
Thus, the first answer is correct.

Formula for the circumference of a circle:
C = πd or C = 2πr
[C = circumference π(pi) d = diameter r = radius(half the diameter)]
You know:
d = 5 feet
and you're using 3.14 for π, so substitute/plug it into the equation
C = πd
C = (3.14)(5)
C = 15.7 feet Your answer is B
Yes it is an isosceles trapezoid
