Answer:

$\frac{7}{x+7}$

Step-by-step explanation:

Step 1: Pull a 7 from the top

$\frac{7x + 42}{x^2 + 13x + 42}$

$\frac{7(x + 6)}{x^2 + 13x + 42}$

Step 2: Factor the bottom

$\frac{7(x + 6)}{(x + 7)(x + 6)}$

Step 3: Cancel the top (x+6) and the bottom (x+6)

$\frac{7}{x+7}$

Answer: $\frac{7}{x+7}$

kodGreya [7K]

Please use * to denote mult. here, not "x." "x" is your variable and cannnot also be a symbol for mult.

f(x)g(x) = 3x^3 - 5x^2.

Now let x = 3:

(f*g)(3) = 3(3)^3 - 5(3)^2 = 81-45 = 36 (answer)

Answer:

48 ft

Step-by-step explanation:

For the quadratic ax^2 +bx +c, the axis of symmetry is x = -b/(2a). For the given quadratic, which defines a parabola opening downward, the axis of symmetry defines the time at which the maximum height is reached.

t = -48/(2(-16)) = 1.5

Then the maximum height is ...

f(1.5) = (-16·1.5 +48)1.5 +12 = (24·1.5) +12

f(1.5) = 48

The maximum height the object will reach is 48 feet.
