Add or subtract numbers from both sides
the picture in the attached figure
we know that
area of the triangle is equal to

in this problem
A=47 in²
b=x
h=x
so

therefore
the answer is
x=9.7 in
Step-by-step explanation:
Nicole starts with the budget:
$395
Now, she only expects to pay half the deposit;
$72 ÷ 2 = $36
Subtract this from the budget:
$395 - $36 = $359
Divide by cost per hour:
$359 ÷ $60 = 5.983333... (3 repeating)
This means, Nicole can rent a <em>maximum</em><em> </em>of 5 hours with her budget. The inequality would be

Explanation:
Midline: it is a horizontal line where half of the function above it and half of the function is below it.
Amplitude: It means how far the function varies from the midline to the above and below.
Period: the distance between two consecutive maximum points (minimum points).
3) From the graph,

Answer: Midline=1
1) Amplitude

2) Periods

4) The trigonometric equation is,
