Answer:
10
Step-by-step explanation:
let s = total songs sung at the concert
If it took 1/8 to sing one song, it would take 1/8 x s hours to sing s songs
= 
1/8 s = 5/4
Divide both sides of the equation by 8
s = 5/4 x 8
s = 10
Answer:144
Step-by-step explanation:
X+6+ X+6+ X+6+ X+6
4x+24
Get the x alone so you divide the 4 on both sides.
24/4=6
X=6
Area
(X+6)(X+6)
X=6 Plug to the Equation So it looks like this
(6+6=12)(6+6=12)
12x12=144
Answer 144
In exponent form It would look like this
