Sophie [7]

Answer:

6 hours

Step-by-step explanation:

We know that:

Samantha = 15 + 2x
Matt = 3 + 4x
Samantha = Matt
[x = Number of hours]

Solution:

15 + 2x = 3 + 4x
=> 15 - 3 = -2x + 4x
=> 12 = 2x
=> x = 6

Hence, after 6 hours of work, Samantha and Matt will have the same amount.

$15x^2+14x-49=0\\\\
Terms:\\
a=15\ \ \ \ b=14\ \ \ \ c=-49\\
Quadratic\ Formula:\\\\
x=\dfrac{-b\pm\sqrt{b^2-4ac}}{2a}\\\\
x=\dfrac{-14\pm\sqrt{196+2,940}}{30}\\\\
x=\dfrac{-14\pm\sqrt{3,136}}{30}\\\\
x=\dfrac{-14\pm56}{30}$

$Roots:\\\\
x'=\dfrac{-14+56}{30}\\\\
x'=\dfrac{42}{30}\\\\
x'=\dfrac{21}{15}\\\\
\boxed{x'=\dfrac{7}{5}}\\\\\\\\
x''=\dfrac{-14-56}{30}\\\\
x''=\dfrac{-70}{30}\\\\
\boxed{x''=\dfrac{-7}{3}}$
