Answer:
the answer is 12!
Explanation: they are squared which are on the line of x
Answer:
Option A
Step-by-step explanation:
We need to find two expressions that, when simplified, give the same results.
1) First, simplify the expression stated in the question. Multiply each of the terms in the parentheses by the number that is next to them. This would mean you have to multiply both 9x and -6 by 
. You also have to multiply 
and 
by 4. Then, simplify.
2) Now, combine the like terms.
So, we need to find which of the expressions listed equal 8x - 6.
3) Let's try option A. Do the same as before. Multiply each of the terms in the parentheses by the number that is next to them. So, multiply 4x and -12 by 
. Also, multiply 30x and 18 by 
. Then, combine like terms and simplify.
This also equals 8x - 6. Therefore, option A is the answer.
-7 and positive 6. if you multiply a negative by a positive it will always be a negative.
It should be noted that the z score for Thomas test grade is 0.237.
<h3>How to illustrate the information?</h3>
From the information, Thomas took a test in Social Studies and earned a 74.8 and there is the fact that all the students' test grades in the Social Studies class had a mean of 72.6 and a standard deviation of 9.3,
Therefore, the z score for Thomas test grade will be:
= Test score - Mean / Standard deviation
= 74.8 - 72.6 / 9.3
= 0.237.
Therefore, it should be noted that the z score for Thomas test grade is 0.237.

Thomas and Pablo began arguing about who did better on their tests, but they couldn't decide who did better given that they took different tests. Thomas took a test in Social Studies and earned a 74.8, and Pablo took a test in Science and earned a 64.1. Use the fact that all the students' test grades in the Social Studies class had a mean of 72.6 and a standard deviation of 9.3, and all the students' test grades in Science had a mean of 61.1 and a standard deviation of 9.8 to answer the following questions.
Calculate the z score for Thomas test grade.
