Well if the room is square then you ned to find the square root of the area.
Find 
|2x-3| + 1 = 6
1) |2x-3| + 1 (-1) = 6 (-1)
2x-3 = 5
2) 2x-3 (+3) = 5 (+3)
2x = 8
3) 2x(/2) = 8(/2)
x = 4
Answer:
m = 7h + 10
Step-by-step explanation:
Since m is representing the total amount of money he earned, we will leave that on one side. If h is the number of hours we worked, the coefficient of h is 7 because he earns 7 dollars an hour. The ten dollar tip is independent from the variables.
Step 1) Divide up the figure
In this figure, there is a triangle, a small rectangle, and two larger rectangles. The triangle is 6 in x 9 in, the small rectangle is 3 in x 18 in, one of the large rectangles (center) is 8 in x 14 in, and the other large rectangle (bottom) is 5 in x 9 in.
Step 2) Find the area of each shape in the figure
Triangle: A = 1/2 x 6 x 9 = 27
Small rectangle: A = 3 x 18 = 54
Large rectangle (center): A = 8 x 14 = 112
Large rectangle (bottom): A = 5 x 9 = 45
Step 3) Add the area of each shape together
A = 27 + 54 + 112 + 45 = 238 square inches
Hope this helps! :)
N=8+d
10d+5n=145
divide 2nd equaiton by 5 to make nicer and easier
2d+n=29
subsitute 8+d for n in 2nd equation
2d+8+d=29
3d+8=29
minus 8 both sides
3d=21
divide by 3
d=7
sub back
n=8+d
n=8+7
n=15
