<h3>Answer = -5</h3>
════════════════════
<h3>Known</h3>
g(x) = -2x - 11
════════════════════
<h3>Question</h3>
g(-3) = ..?
════════════════════
<h3>Way to do</h3>
#since x inside (x) change into (-3) then it means that you only need to change x into -3
g(-3) = -2(-3) - 11
g(-3) = 6 - 11
g(-3) = -5

I got 60 for the answer. When you plug the number in you use parentheses.
A) Total cost of materials: 145.86 + 52.91 + 17.63 = $216.40
b) Percent cost of hardware: 17.63/216.40 = 0.081
c) Percent cost paint and hardware: (17.63 + 52.91)/216.40 = 0.326
Step-by-step explanation:
Answer:
The other side = 13 feets long
Step-by-step explanation:
Given that :
Scale of drawing : 2 inches represents 5 feets
Area of rectangular room according to scale drawing = 24.96 in²
Length of one side of the room = 12 feets
Length of other side = x
Area of rectangle = Length * width
If :
2 inches = 5 feets
x = 12 feets
x = (12 *2) / 5
x = 4.8 inches
Hence,
For the scaled drawing :
4.8 * width = 24.96
Width = 24.96 / 4.8
Width = 5.2 inches
Converting to feets according to scale:
2 inches = 5 feets
5.2 inches = x feets
x = (5.2 * 5 ) / 2
x = 13 feets
Other side is 13 feets long
