Answer: 576 inches or 48 feet
Step-by-step explanation:
set up a proportion where 
so you get drawingAB = 24 in
actualAB = 18 feet = 18 * 12 in = 216 in
drawing perimeter = 64 in
so plug these in to get
rearrange to get 
and solve to get 576 inches or 576/12 = 48 feet
Since AB is a straight line, and straight lines are 180 degrees, you can add the two 62 degree angles.
62+62=124
180-124=56
angle x is 56 degrees
I will show all the steps to lead to the solution.
1) 10b = 5 (√c + 2) <---- starting equation
2) divide by 5 => 2 b = √c + 2
3) subtract 2 => 2b - 2 = √c
4) raise to the power 2 => (2b - 2)^2 = c, which is the expression given.
Now these are two equivalent forms:
1) extract 2 from the parentheses: c = 4 (b -1)^2
2) expand the parentheses: c = 4b^2 - 8b + 4)
We can sort this out in 2 groups. Group 1 has 5 people and each person has 1 granola bar. Group 2 has 5 people and each person has 0 granola bars. Alright , so group 1 has 5 members and each has 5 granola bars, therefore group 1 has altogether 5 granola bars. On the other hand Group 2 has 5 members but with 0 granola bars each. So in result , Group 1 has more granola bars, having 5 and group 2 having 0. Hope this helped!
In box one you have to distribute so -2(3x-5)= -6x-(-10)
