Answer:

9b + 99

Step-by-step explanation:

You have already seen what the example had done.

First multiply (factorize) 9 to both variables inside the parentheses.

9 · b = 9b

9 · 4 = 36

Now remember to not change the sign in the parentheses

9b + 36 + 63

You can now add 63 and 36 together.

63 + 36 = 99

So,

9b + 99

It is still "plus" sign because the number 99 is a positive.

BlackZzzverrR [31]
<span>33.75/45.00 x 100 = 75%

That means that the price has been marked down by 100-75 = 25% because that is how much of the original you are NOT paying.

Therefore, the answer is 25%. </span>

Why not?<br> If 4 + 6 = 10, does (4 + 6) X 3 = 10 X 3? Why<br> or why not?
IgorLugansk [536]

Answer:

It would be 10*3

Step-by-step explanation:

If we follow the rule of BIDMAS or BODMAS, they both have Brackets to be done first.

By meaning we must do 4+6 as it is in the bracket. Then we multiply our answer by 3.
