Answer:

$\frac{1}{30}$

Step-by-step explanation:

Change the mixed number into an improper fraction

1 $\frac{3}{10}$ = $\frac{13}{10}$ , hence

$\frac{13}{10}$ ÷ 39

To divide, leave the first fraction, change division to multiplication and turn 39 upside down, that is

= $\frac{13}{10}$ × $\frac{1}{39}$

cancel the 13 and 39 by dividing both by 13

= $\frac{1}{10(3)}$ = $\frac{1}{30}$

Tina was asked to determine the possible dimensions of a given rectangle whose area is 12a4b3-18a6b3-72a7b3. Tina stated that th

Rufina [12.5K]

Answer:

Tina is correct

Step-by-step explanation:

Given

$Area = 12a^4b^3 - 18a^6b^3 - 72a^7b^3$

Required

State if $3a^4b^3(4-6a^2-24a^3)$ is a possible dimension

To do this, we simply expand $3a^4b^3(4-6a^2-24a^3)$

$3a^4b^3(4-6a^2-24a^3)$

$3a^4b^3 * 4-3a^4b^3 * 6a^2-3a^4b^3 * 24a^3$

$12a^4b^3 - 18a^{4+2}b^3 * -72a^{4+3}b^3$

$12a^4b^3 - 18a^{6}b^3 * -72a^{7}b^3$

By comparison, the result of the expansion

$12a^4b^3 - 18a^{6}b^3 * -72a^{7}b^3$

and the given expression

$Area = 12a^4b^3 - 18a^6b^3 - 72a^7b^3$

are the same.

<em>Hence, Tina is correct</em>
