Daniel: 3/4=.75 = 75%
Jacob: 5/12= .41 = 41%
So it would be Jacob that is faster
-5 is the answer I’m pretty sure...
<span>(5x^2+8x+6) + (8x^2+6x-6) - </span><span>(12x+9)
= </span>5x^2 + 8x+ 6 + 8x^2 + 6x - 6 - 12x - 9
= 13x^2 + 2x - 9
answer
13x^2 + 2x - 9
x = 160 gal
y = 80 gal
160 gallons of water and 80 gallons of premium antifreeze solution must be mixed.
