Question

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

Answer 1

the answer is the 2nd option

Explanation:

i just took the test

Answer 2

`(5t^2+54t)/(10t^2)`

Explanation:

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

`(14t)/(10t^2)+(5t^2+40t)/(10t^2)`

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

`(14t+5t^2+40t)/(10t^2)`

Regroup the terms in the numerator and add;

`(5t^2+40t+14t)/(10t^2)`

`=(5t^2+54t)/(10t^2)`
