Simplify square root of 63

Step-by-step explanation: To simplify the square root of 63, let’s first start by setting up a factor tree. A factor tree is very useful when finding the prime factorization of a number and can help us see it visually. Once we make our factor tree, we need to find out what two numbers multiplied together will give us a product of 63.

In this case, 9 multiplied by 7 will give us a product of 63 so we can write both 9 and 7 under 63.

Next, we can factor 9 because 7 cannot be factored other than itself and 1. The number 9 factors into 3 and 3 so we can write these numbers under 9. Now that we found the factors, we are done with our factor tree. Notice that we have two pairs of 3’s in our factor tree so a 3 can come outside of the radical.

Also, there is a 7 in our factor tree which does not pair up so it can stay inside of the radical. Therefore, the answer to this problem is .

choice b is correct

step-by-step explanation:

we have been given the following system of linear inequalities;

we are required to graphically determine the solution to these system of inequalities. using a graphing tool, the solution is as shown in the attachment below;

exa:

)

3+11

14

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
