Answer:
To check if a given value is a solution to an equation:
Evaluate the left-hand side expression at the given value to get a number.
Evaluate the right-hand side expression at the given value to get a number.
See if the numbers match.
75% of 56 is .75 * 56
.75 * 56 = 42
Because you are decreasing, you subtract 42 from 56.
56 - 42 = 14
A 75% decrease of 56 books would leave 14 books.

Step-by-step explanation:
If you want to translate this figure 6 units right and 6 down, all you have to do is take each point and add 6 to it's x value and subtract 6 from its y value.
I labeled them left to right
A -8, 4 to -2, -2
B -3, 4 to 3, -2
C -2, 1 to 4, -5

Answer: 1350 square inches</h3>
Work Shown:
s = side length = 15 inches
SA = surface area of the cube
SA = 6s^2
SA = 6*15^2
SA = 6*225
SA = 1350
The surface area is 1350 square inches.
Note the formula has us compute the area of each square face, which is s*s = s^2. Then we multiply by 6 since there are 6 identical square faces on the cube.
First, determine the volume of the room by multiplying its dimensions such that,
Volume = Length x Width x Height
Substituting,
volume = (16.5 ft)(7.5 ft)(8 ft)
volume = 990 ft³
To determine the mass, we multiply the obtained volume by the density.
mass = (990 ft³)(27 lb/ 10 ft³)
mass = 2673 lb
Answer: 2673 lb
