(-4-(2))/(7-5)

(-6)/(2)

-3

Factor the binomial 9t to second power,-4 =

Naily [24]

Using subtraction of perfect squares, it is found that the factored expression is:

9t² - 4 = (3t - 2)(3t + 2).

<h3>What is the subtraction of perfect squares factoring?</h3>

It is given as follows:

a^2 - b^2 = (a - b)(a + b)

In this problem, the binomial is given as follows:

9t² - 4.

Hence:

a² = 9t² -> a = 3t.

b² = 4 -> b = 2.

Hence the factored expression is:

9t² - 4 = (3t - 2)(3t + 2).

own Everything's Coming Up Roses flower shop. Your employee makes 4 deliveries per hour. The distance between the shop and the f

erma4kov [3.2K]

The journey is broken down into five segment

Shop - first delivery = $12 \frac{1}{3}$ miles
First delivery - second delivery = $8 \frac{3}{4}$
Second delivery - third delivery = $17 \frac{2}{8}$
Third delivery - fourth delivery = $23 \frac{2}{3}$
Fourth delivery - shop = $10 \frac{5}{10}$

The average distance for each segment are:
$[12 \frac{1}{3}+8 \frac{3}{4}+17 \frac{2}{8}+23 \frac{2}{3}+10 \frac{5}{10} ]$ ÷ $5$

$\frac{145}{2}$ ÷5 = $\frac{29}{2}=14 \frac{1}{2}$
