Answer:
2(x-3)+2x=54
Step-by-step explanation:
Take the side length of the rectangle as x
For the perimeter we must have - as we also have 2 lots of a side that is 3 inches shorter than x.

Answer:
the measurement of x is 30 degrees
Answer: The choice will be any equation where the slope is the same and the y-intercept is different.

Step-by-step explanation: Using slope-intercept form, y = mx + b,
m is the slope, b is the y-intercept.
Parallel lines will have the same slope.
So, you are looking for another equation that has 5/6 as the coefficient of x.
It could be an equation in the form 6y + 5x = _b_ where the constant, b, could be anything except -42, as that would be an identical line, not parallel.
-3/5x + 1/5 > 7/20
-3/5x > 7/20 - 1/5
-3/5x > 7/20 - 4/20
-3/5x > 3/20
x < 3/20 * - 5/3
x < -15/60 reduces to -1/4
