Answer:
x = -1
x = -2/3 = -0.667
Step-by-step explanation:
Answer:
From largest to smallest: FG, FH, GH
Step-by-step explanation:
Given




Required
Order the sides in descending order
First, we need to solve for x.
Perimeter of FGH is calculated as thus:

Substitute values for FG, GH, FH and Perimeter

Reorder

Divide through by 24


Substitute 4 for x in FG, GH and FH












In order of arrangement in descending order, we have:

Y = 2x^2 - 4x + 2
y = 2(x^2 - 2x + 1)
2(x - 1)^2 = = 0
so the graph will just touch the x axis at x = 1
So there is one zero duplicity 2.
Supplementary angles are 180 in total, so to find the answer you do 180-10, which equals 170. The answer is 170
Remember the are of a square is the side of a square squared.
This meant that this square's area=5^2=25
Done!
