Simplify the rational expression. state any excluded values. 2x/−5x +x^2

The given expression is

First we need to factor the denominator. And x is common in the denominator .

So we will get

Cancelling the common x of the numerator and denominator

And that's the simplified form .

Excluded values

Denominator should not be zero .

So the excluded values are x=0,5 .

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet
