The amount of metal he will need to cover the back of the shelves is 180 inches².
The figure above is like a composite figure. Therefore, lets find the area.
<h3>Area of the composite figure</h3>
The area of the figure is the sum of the whole individual 2 dimensional shapes in the composite figure.
Therefore, two rectangles can be drawn from it.
area of rectangle = lw
where
l = length
w = width
Therefore,
area of rectangle 1 = 9 × 8 = 72 inches²
area of rectangle 2 = 6 × 18 = 108 inches²
Total area = 108 + 72 = 180 inches²
Therefore, the amount of metal he will need to cover the back of the shelves is 180 inches².

I don’t understand what your asking. there is no numbers involved or a equation.
Answer:
Step-by-step explanation:
(f - g)(x) = x - 3
Line up these functions vertically:
f(x) = 3x - 2
-g(x) = -(2x + 1)
--------------------
(f - g)(x) = x - 3 (answer)
Answer:
<h2>x = 5/7</h2>
Step-by-step explanation:
-4x + 1 = 3x - 4 <em>subtract 1 from both sides</em>
-4x = 3x - 5<em> subtract 3x from both sides</em>
-7x = -5<em> </em>divide both sides by (-7)
<em>x = 5/7</em>
