The denominator of a fraction in simplest form is greater than the numerator by 3. If 7 is added to the numerator, and 5 added

jok3333 [9.3K]

So.. if we take the numerator to be say "a", then the denominator will be "a+3"

$\bf \cfrac{a}{a+3}\textit{ if we add }\frac{1}{2}\textit{ we get then }\cfrac{a+7}{a+3+5}
\\\\\\
thus\implies \cfrac{a}{a+3}+\cfrac{1}{2}=\cfrac{a+7}{a+8}\\\\
-----------------------------\\\\
\cfrac{a+3+2a}{2(a+3)}=\cfrac{a+7}{a+8}\implies \cfrac{3a+3}{2a+6}=\cfrac{a+7}{a+8}
\\\\\\
3a^2+24a+3a+24=2a^2+14a+6a+42
\\\\\\
a^2+7a-18=0\implies (a+9)(a-2)=0
\\\\\\
a=
\begin{cases}
2\implies &\frac{2}{5}\\\\
-9\implies &\frac{3}{2}
\end{cases}$

either of those two fractions will do

Can anyone help me with 15a b c

Ilya [14]

The 3r would be the independent variable and m=30 is the dependent variable. Double check the answer though.

Use the formula SA=6s2 , where SA is the surface area and s is the edge length of the cube, to solve this problem.

Irina-Kira [14]

Using the SA formula you'll have to substitute in the edge length for s.

SA = 6(312)²
SA = 584064

The surface area is 584,064 feet²

Hope this helps :)
