Answer:
158
Step-by-step explanation:
5*8=40
8*3=24
3*5=15
Each of these measurements gets added twice, becasue there are 6 faces on a rectangular prism.
40 + 40 + 24 + 24 + 15 + 15 = 158
Answer:
The inequality is 
Step-by-step explanation:
Total time:
The total time to complete the test is the sum of the number of multiple-choice questions multiplied by the time it takes to solve each and the number of short-answer questions multiply by the time it takes to solve each.
In this question:
Same number(n) of both.
Multiple-choice takes 2 minutes, short-answer takes 3.5 minutes. The total time is given by:

Write an inequality to determine how many questions, n, the teacher can include if the test must take students less than 45 minutes to complete.?
This means that:

So

The inequality is 
Having The Lack Of Information, We Can Only Give You An Equation.
So:
Quotient = Division.
R / 12 Is The Equation.
(If This Is Not What You Need, Put In More Info, And I Can Solve It. ;) <span />
Step-by-step explanation:
<em>the value of x is 8</em>
8^(2) = 64
the value of y is 11
11^(2) = 121
x - y
= 8 - 11
= -3
