Question

Elias is adding and . He finds the LCD to be 10t2 and uses multiplication to find equivalent expressions.

Answer 1

Answer:

$\frac{5t^2+54t}{10t^2}$

Step-by-step explanation:

So, we want to find the sum of the equivalent expression;

$\frac{14t}{10t^2}+\frac{5t^2+40t}{10t^2}$

Since the two fractions are equivalent, we keep one denominator and add the numerators.

$\frac{14t+5t^2+40t}{10t^2}$

Regroup the terms in the numerator and add;

$\frac{5t^2+40t+14t}{10t^2}$

$=\frac{5t^2+54t}{10t^2}$
