Find the sum of the terms.
kow [346]

Answer:

C

Step-by-step explanation:

Given

\frac{x}{x^2+3x+2} + \frac{3}{x+1} ← factor the denominator of first fraction

= \frac{x}{(x+1)(x+2)} + \frac{3}{x+1}

Multiply the numerator/ denominator of second fraction by (x + 2)

= \frac{x}{(x+1)(x+2)} + \frac{3(x+2)}{(x+1)(x+2)}

The denominators are now common, so add the numerators leaving the denominator, that is

= \frac{x+3x+6}{(x+1)(x+2)}

= \frac{4x+6}{(x+1)(x+2)} → with numerator 4x + 6 → C

<em>t</em> = - \frac{80}{2(-16)} = \frac{5}{2} = <em>2.5 sec. </em>

<em>h</em> = - 16(2.5)² + 80(2.5) = - 100 + 200 = <em>100 ft</em>.
