Well the answer options are a bit confusing but the steps are 1, 2, & 3.
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:

Answer:
0.6 x 25 = x
Step-by-step explanation:
60% of 25
= 60/100 x 25
= 0.6 x 25
= 15
Though the question states as in a "select-all question," Only answer 0.6 x 25 = x will be correct.
Lets Anna's age = A
Mr. Goldstein age = G
Mr. Goldstein is 4 times as old as his daughter Anna.
So G= 4A
In 4 years, he will be 3 times as old as Anna
we add 4 with Both their ages
G + 4 = three times of A + 4
G + 4= 3(A + 4)
We know G= 4A, replace it in above equation
4A + 4= 3(A + 4)
4A + 4= 3A + 12
Subtract 3A from both sides
A + 4 = 12
Subtract 4 from both sides
A = 8
So Anna's age = 8 years
