Answer:
11a. 15x + 6
11b. x + 8 < 16 or x + 8 - 16
12. 3x + 15 + 5x = 8x + 15
13. 7x + 31
Step-by-step explanation:
Hello!
You first have to find the total amount of apartments
35 + 55 = 90
There are 90 apartments
Then you find the percentage of them have a balcony
You do this by taking the amount of apartments that have a balcony over the total amount of apartments
35/90 = 0.39
0.39 as a percent is 39%
The answer is 39/100 or 39%
Hope this helps!

Answer:
see below
Step-by-step explanation:
2x^2 -2x-12 = 0
Factor out 2
2(x^2 - x -6) = 0
Factor inside the parentheses
2( x-3)(x-2)=0
Using the zero product property
x-3 =0 x-2=0
x=3 x=2
The graph crosses the x axis when x=3 and x=2
