Answer:

x = \frac{mn(q-p)}{n-m}

Step-by-step explanation:

collect the fractional terms on the left side of the equation and other terms on the right side

subtract \frac{x-n}{n} from both sides

\frac{x-m}{m} - \frac{x-n}{n} + p = q

subtract p from both sides

\frac{x-m}{m} - \frac{x-n}{n} = q - p

We require the fractions to have a common denominator of mn

multiply the numerator/denominator of the first fraction by n and the numerator/denominator of the second fraction by m

\frac{n(x-m)}{mn} - \frac{m(x-n)}{mn} = q - p

distribute and simplify the numerators of the fractions

\frac{nx-nm-mx+mn}{mn} = q - p

\frac{nx-mx}{mn} = q - p

factor out x from each term on the numerator

\frac{x(n-m)}{mn} = q - p

multiply both sides by mn

x(n - m) = mn(q - p)

divide both sides by (n - m)

x = \frac{mn(q-p)}{n-m} → n ≠ m

VLD [36.1K]

Answer:

The answer to part A is 15 cm because you would first divide 16 by two to find the base of one triangle. Then you would do the pythagorean theorem to find the height. <em> I don't know if that would help.</em>

The answer to part B is 240 cm squared because you would find the area of one right triangle and multiply it by 4 to find the area of all the sides of the box.
