Answer:

8r + 14s - 7T

Step-by-step explanation:

Hello!

We have to make sure the terms are like terms before we add them.

Like terms are terms with the same variable so we can add r's with r's, t's with t's, etc.

There are two r's and two s's so we can simplify those

12r - 4r = 8r

5s + 9s = 14s

Now put these all together with the T in the original equation to get the answer

8r + 14s - 7T

Hope this helps!

Answer: To simplify this problem you combine the like terms in the equation (numbers with the same variables.)

Demo: 12r + -4r = 8r

Morgarella [4.7K]
Since there are a total of 48 beads and each bead will either be blue or yellow, in order to find out how many of each colour bead she will use, do the following:

Divide 48 by 3 to get 16 yellow beads.

Now that you know how many yellow beads there are, just subtract that from 48:
48 - 16 = 32

Therefore, she will use 16 yellow beads and 32 blue beads.

The answer is D
if the legs are 5 and 4 cm the equation to find the hypotenuse would be 5^2+4^2=c^c
5 squared is 25 and 4 squared is 16 that gives you 41, normally you would square root the 41 but it gives you a decimal number
