Answer:
x = 26
Step-by-step explanation:
The midsegment is parallel to the side KM and half its length, thus
KM = x = 2 × 13 = 26

<u><em>The correct question is</em></u>
Find the volume and the surface area of a rectangular prism. Bases are squares with sides that measure 27 inches. The height is 12 inches.
Part 1) Find the volume of the prism
The volume of the prism is equal to
where
B is the area of the base
h is the height of the prism
<em>Find the area of the base B</em>
---> the base is a square
we have
substitute
Part 2) Find the surface area of the prism
The surface area of the prism is equal to
where
B is the area of the base
P is the perimeter of the base
h is the height of the prism
<em>Find the perimeter of the base P</em>
<em></em>
<em></em>
substitute the values in the formula
Answer:
Step-by-step explanation:
Let’s start seeing what happens to the left. It stops before x = -1, but it continues to do down
so as x approaches -1, y approaches -oo
Now we have to see what happens to the right. In the case the graph doesn’t stop and it keeps to go up
so as x approaches oo, y approaches oo
Answer:176 psychology textbooks and 98 Biology textbooks were sold.
Step-by-step explanation:
Let x represent the number of psychology textbooks that were sold.
Let y represent the number of biology textbooks that were sold.
textbook store sold a combined total of 274 psychology and biology textbooks in a week. This means that
x + y = 274 - - - - - - - - - - -1
The number of psychology textbooks sold was 78 more than the number of biology textbooks sold. This means that
x = y + 78
Substituting x = y + 78 into equation 1, it becomes
y + 78 + y = 274
2y = 274 - 78
2y = 196
y = 98
x = y + 78 = 98 + 78
x = 176
