Answer:
C. 52
Step-by-step explanation:
First, find the base of the triangle. You can do this by looking at the top of the figure. 14 inches is the width of the rectangle, and 20 inches is the width of the rectangle and the base of the triangle. You can find the base of the triangle by subtracting.

The base of the triangle is 6. The height of the triangle is equal to the height of the rectangle, 8. Now you need to find the hypotenuse of the triangle using the Pythagorean theorem:

c is the hypotenuse. Find c:

The hypotenuse of the triangle is 10. Now that you know the hypotenuse, you can find the perimeter. Add all the sides:

The perimeter is 52 inches.
Answer:
The number of lower-priced speaker sold was 28
Step-by-step explanation:
<u><em>The complete question is</em></u>
An online store sells two types of speaker. The higher-priced speaker sells for $170 and the lower-priced speaker sells for $90. Last week the store sold four times as many lower-priced speaker as higher-priced speaker. Combined sales totaled $3,710. How many lower-priced speaker did it sell?
Let
x ----> the number of higher-priced speaker sold
y ----> the number of lower-priced speaker sold
we know that
Last week the store sold four times as many lower-priced speaker as higher-priced speaker
so
----> equation A
Combined sales totaled $3,710
so
----> equation B
Solve the system by graphing
Remember that the solution is the intersection point both graphs
Using a graphing tool
The solution is the point (7,28)
see the attached figure
therefore
The number of lower-priced speaker sold was 28 and the number of higher-priced speaker sold was 7
The answer is b because it has the 3 with 6 corresponding.<span />
