Ab+ac=a(b+c)
a is a common factor to both
find greatest common factor
factor each
18x²=2*3*3*x*x
6x=2*3*x
gcf=2*3*x=6x
so
18x²+6x=6x(3x)+6x(1)=6x(3x+1)
8(x+6) = 8x + 48.
8(x+6) is just the factored form.
Answer:
<u>Given</u>: base = 10.4ft, height = 12.5
Area of octagon = 8(1/2 × b × h)
- 8(1/2 × 10.4 × 12.5)
- 520ft²
Volume of pool = 520ft² × 3ft
Now, 1 cubic ft takes 7.5 gallons to fill.
Therefore, 1560 cubic ft takes,
So, <u>Correct choice</u> - [D] 11,700.
