Answer:

Fiona earns $2/hour more than Philip.

Step-by-step explanation:

y = 12x shows a slope of 12. That slope is the hourly salary.

Philip earns $12/hour.

Fiona:

$42/(3 hours) = $14/hour

Fiona earns $14/hour

14 - 12 = 2

Fiona earns $2/hour more than Philip.

How would you factor
Svetach [21]
\bf 4x^3+2x^2+2x\implies 2x(2x^2+x+1)

so in short, the only factoring doable to it, without any complex factors, is that of taking the common factor of 2x.

now, the trinomial of 2x²+x+1, will not give us any "real roots", just complex or "imaginary" ones.

if you have already covered the quadratic formula, you could test with that, or you can also check that trinomial's discriminant, and notice that it will give you a negative value.

\bf \begin{array}{llcccll}
& 2 x^2& +1 x& +1\\
&\uparrow &\uparrow &\uparrow \\
&a&b&c
\end{array}\qquad \qquad 1^2-4(2)(1)
\\\\\\
discriminant\implies b^2-4ac=
\begin{cases}
0&\textit{one solution}\\
positive&\textit{two solutions}\\
negative&\textit{no solution}
\end{cases}

Kobotan [32]

Answer:

Ratio is :  5/4  or  5 : 4

Step-by-step explanation:

The ratio of the number of stories in the first building to the number of stories in the second building :  

    60 : 48    or 60/48

Both numbers have 3 and 4 as common factors. So

  3 * 4 * 5 :  3 * 4 * 4

 5 : 4  is the ratio in the simplest terms striking of the common factors.
