Adrian is putting streamers across the ceiling of his dining room to decorate for his nephew’s birthday party. the ceiling is rectangular. its area is 122.5 square feet, and its width is 7 feet. how long should adrian cut a streamer that will run the length of the ceiling?

step-by-step explanation:

20% of 120 is 24. if you subtract 24 from 120 you get 96

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions
