If we look at his calculations
2((9)(20) is the front an back rectangle
2((9)(34)) is the side rectangles
(34)(20) is the bottom
2(1/2(20(24)) is te front and top triangles
and the last one assumes that they are triangles which is incorrect
answer is D
Answer:
Step-by-step explanation:
The sum of the interior angles of a triangle add up to 
. Therefore, an equiangular triangle will have each of its angles equal to 
. We can then set up the following equation:
.

Given Information
----------------------------------------------------------------
Adrian can run 3/4 mile in 1 morning.
----------------------------------------------------------------
Find how long he needs to run 1 mile
----------------------------------------------------------------
3/4 miles = 1 morning
[ Divide by 3/4 on both side ]
3/4 ÷ 3/4 miles = 1 ÷ 3/4
1 miles = 4/3 morning
----------------------------------------------------------------
Find how long he needs to take to run 3 miles
----------------------------------------------------------------
1 miles = 4/3 morning
[ multiply by 3 through ]
3 miles = 4/3 x 3
3 miles = 4 mornings
----------------------------------------------------------------
Answer : 4 mornings
----------------------------------------------------------------
<span>5*s-(4*s)-(1/2) = -1/4-(4/8) // + -1/4-(4/8)
5*s-(4*s)-(1/2)-(-1/4)+4/8 = 0
5*s-4*s-1/2+1/4+4/8 = 0
s+1/4 = 0 // - 1/4
s = -1/4
s = -1/4
