Answer:
x=3
Step-by-step explanation:
The square root of 225 is 15
so 15=4x+3
-3 -3
12=4x
If 12=4x then x=3
Answer:
Add the equations in order to solve for the first variable. Plug this value into the other equations in order to solve for the remaining variables.
X = 1
Y = 2
-16y = -12x + 48
y = .75x -3
The rate of change is .75 or 3/4.
4(x+7)=8x-20
4x+28=8x-20
28=4x-20
48=4x
x=12
Area = length * width
Area = (n yds + 40 yds) * 30 yds
or
Area = (30 yds * n yards) + (30 yds * 40 yards)
This is if you add the area of the rides to the area of the arcade (the first parenthesis is the rides, the second is the arcade.)
