15 percent is categorical data
<span>4x^2-x-3=0
let us rewrite the equation in much simplified form:
x^2 - 0.25x - 0.75 = 0
</span><span>x^2 - 0.25x = 0.75
</span>x^2 - 1/4 x + 1/64 =3/4 + 1/64
(x-1/8)^2 = 49/64
x−<span>1/8</span>=±<span>49/64
</span><span><span>x1</span>=−<span>3/4
</span></span><span><span>x2</span>=1</span>
3 to 5 feet is the ratio in lowest form
15-3b=63
subtract 15 from both sides
-3b=48
divide -3 from both sides
b= -16
