Answer:

(f×g)(x) = 2x³ +x² -14x -7

Step-by-step explanation:

(f×g)(x) = f(x)×g(x) = (2x +1)×(x² -7)

= 2x(x² -7) +1(x² -7)

= 2x³ -14x +x² -7

(f×g)(x) = 2x³ +x² -14x -7

24 x 12 1/2 x 12 3/4 what is the volume of the fish tank

hjlf

Answer:

The volume is 3825 cubic units

Step-by-step explanation:

We were given the dimensions as:

$24 \times 12 \frac{1}{2} \times 12 \frac{3}{4}$

Change the numbers to improper fractions

$24 \times \frac{25}{2} \times \frac{51}{4}$

We cancel out to get

$3 \times 25 \times 51$
