The mean number of people per day visiting an art show in July was 120. If 30 more people each day visited the museum in August, what was the mean number of people per day visiting in August? A. 620
B. 150
C. 650
D. 120

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

there are many solutions.

step-by-step explanation:

step 1: simplify both sides of the equation.

4x+6=4x^2+10x−4

step 2: subtract 4x^2+10x-4 from both sides.

4x+6−(4x^2+10x−4)=4x^2+10x−4−(4x^2+10x−4)

−4x^2−6x+10=0

step 3: factor left side of equation.

−2(2x+5)(x−1)=0

step 4: set factors equal to 0.

x=-5/2 or x=1
