Help plsss thank youuuu

MArishka [77]

<u>Answer:</u>

A. (x+5)

<u>Step-by-step explanation:</u>

We are given a quadratic expression $x^2+8x+15$ which we will factorize to see which of the given options is a binomial factor of it.

$x^2+8x+15$

Finding the factors of 15 such that when added, they give a result of 8.

$x^2+3x+5x+15\\\\x(x+3)+5(x+3)\\\\(x+3)(x+5)$

Therefore, we can see that $(x+5)$ is that binomial factor that is present in the given options so option A. (x+5) is the correct answer.

What is the approximate distance between the points (-3,-4)(-8,1) on a coordinate grid?

Alex

$\bf ~~~~~~~~~~~~\textit{distance between 2 points} \\\\ (\stackrel{x_1}{-3}~,~\stackrel{y_1}{-4})\qquad (\stackrel{x_2}{-8}~,~\stackrel{y_2}{1})\qquad \qquad d = \sqrt{( x_2- x_1)^2 + ( y_2- y_1)^2} \\\\\\ d=\sqrt{[-8-(-3)]^2+[1-(-4)]^2}\implies d=\sqrt{(-8+3)^2+(1+4)^2} \\\\\\ d=\sqrt{25+25}\implies d=\sqrt{50}\implies d\approx 7.071$

Which of the following correctly uses absolute value to show the distance between -60 and 13? (5 points)

Sauron [17]

Answer:

l-60 – 13| = |-73| = 73 units

Step-by-step explanation:

Required

Distance between -60 and 13

Using absolute values, distance is calculated as:

$Distance = |Start - End|$

Where

$Start = -60$

$End = 13$

So, we have:

$Distance = |-60 - 13|$

$Distance = |-73|$

Take absolute value of -73

$Distance = 73$

<em>Hence, option A answers the question</em>
