Answer:

Question 8.) Choice d.) 4 + x + 6x = 4 + 7x

Question 9.) Choice b.) 18 - 15 + 4n + 5n simplifies to 9n + 3

Step-by-step explanation:

For the first question, like terms are terms that have the same variables, and not necessarily the same coefficient numbers.

first problem, x + y + xy all have unique terms. x is different from y and is different from xy

so it cannot be A.

Choice d. has like terms x and 6x so 4 + x + 6x can simplify to 4 + 7x

Choice b.) 18 - 15 + 4n + 5n simplifies to 9n + 3

What is the distance between (4,2) and (-1,-3)

Sati [7]

<h2>Solving for the Distance between two Points</h2><h3>Answer:</h3>

$5 \sqrt{2}$ or $7.071$

<h3>Step-by-step explanation:</h3>

<em>Please refer to my answer from this Question to know more about distances between two points: <u>brainly.com/question/24629826</u></em>

Given:

$(4,2)$

$(-1,-3)$

Solving for the Distance:

$\sqrt{(4-(-1))^2 +(2 -(-3))^2} \\ \sqrt{(4 +1)^2 +(2 +3)^2} \\ \sqrt{5^2 +5^2} \\ \sqrt{25 +25} \\ \sqrt{50} \\ \sqrt{25 \cdot 2} \\ 5 \sqrt{2}$

<u>Note:</u>

$5 \sqrt{2} \approx 7.071$
