1 → A

using the ' laws of logarithms '

• log( $x^{n}$ ↔ nlogx

• logx = logy ⇒ x = y

log49 = log7²

log49 = log49 ⇒ 49 = 49 ⇒ 1

35 POINTS HELP PLS!!!!!!

Ronch [10]

The factors illustrate they the sides of the rectangles are:

(x - 1)(x - 2)
(2x - 3)(x + 2)

<h3>How to get the factors?</h3>

The first equation given is x² - 3x + 2.

= x² - 3x + 2.

= x² - x - 2x + 2

= x(x - 1) - 2(x - 1)

= (x - 1)(x - 2)

Therefore, the side lengths are (x - 1) and (x - 2).

In the rectangular figure, the length and width should be the expressions above.

The second equation given is 2x² + x - 6.

= 2x² + x - 6.

= 2x² + 4x - 3x - 6

= 2x(x + 2) - 3(x + 2)

= (2x - 3)(x + 2)

Therefore, the side lengths are (2x - 3) and (x + 2).

In the rectangular figure, the length and width should be the expressions above.

Help! I don’t understand this

Papessa [141]

Answer:

1/2

Step-by-step explanation:

A sample space is a collection or a set of possible outcomes of a random experiment.

I have created the sample space for these data and attached it. As you can see there are 16 possible outcomes.

To find the probability that the total showing is greater than 9, simply identify the number of values in the sample space that are greater than 9.

(I have highlighted these in yellow).

Therefore, P(X>9) = 8/16 = 1/2

About \frac{3}{8}3 8 of the business calls that Ms. Rodriguez makes are long distance calls. How many business calls would you e

Elena L [17]

$\frac{3}{8}x = 32$

multiply both sides by the reciprocal

x = 85⅓

We would expect her to make about 85 business calls in a month.

Step-by-step explanation:

The equation means "3/8 of the unknown total is 32"

When we multiply 3/8 by its reciprocal, it becomes 1 and cancels on the left.

8/3 times 32 is a mixed number, so it is reasonable to round it to a whole number of calls.

I hope I read this question correctly. The coding for the fraction made it a bit confusing.
