Answer:

n = $\frac{14m-P-2A}{4}$

Step-by-step explanation:

Given

$\frac{P}{2}$ + A = 7m - 2n ( multiply through by 2 to clear the fraction )

P + 2A = 14m - 4n ( subtract 14m from both sides )

P + 2A - 14m = - 4n ( multiply through by - 1 )

14m - P - 2A = 4n ( divide both sides by 4 )

$\frac{14m-P-2A}{4}$ = n

Given f(x)=3x^2+5 and g(x)=x−2 . What is (fg)(x) ? 3x^2−x+7 3x^3−6x2+5x−10 −3x^2+x−7 3x^3−10

wolverine [178]

For this case we have that by definition:

$(fg) (x) = f (x) * g (x)$

So:

$(fg) (x) = (3x ^ 2 + 5) (x-2)$

We apply distributive property that states that:

$(a + b) (c + d) = ac + ad + bc + bd$

In addition, we take into account that:

$+ * - = -$

$(fg) (x) = 3x ^ 3-6x ^ 2 + 5x-10$

Answer:

$3x ^ 3-6x ^ 2 + 5x-10$
