the _________ is a number that is multiplied. the number that indicates how many times this number is used as a factor is the ___________

Answers

The  base   is a number that is multiplied. The number that indicates how many times this number is used as a factor is the  exponent  

For example, the number 2^3 expands out to 2*2*2. We have three copies of the base '2' being multiplied.

Another example: 5^2 = 5*5.

Answer:

The "Factor" is a number that is multiplied. The number that indicates how many times this number is used as a factor is the "Exponent".

Step-by-step explanation:

Example: 7 • 7 can be written as 72, 7 is the base and 2 is the exponent. The exponent 2 means there are two factors.

Step-by-step explanation:

[tex]y(x + y) - 1(1 + x)[/tex]

Lets expand it.

[tex] = > xy + {y}^{2} - x - 1[/tex]

Lets re-arrange it.

[tex] = > xy - x + {y}^{2} - 1[/tex]

Lets split [tex] {y}^{2} - 1[/tex]

So,

[tex] = > x(y - 1) + (y + 1)(y - 1)[/tex]

Hey and help me help me help plzzzzzzzzz

Answers

Answer:17

Step-by-step explanation:

First you subtract 13-9 to find the distance between the 2 numbers. That gets you 4 but if the numbers are 2 spaces away from one another then that means that the number line increases by 2. Then you add 4 to 13 and that’s how you get 17.

This recipe makes 18 cupcakes. Deepak only wants to make 12 cupcakes. How much of each ingredient does he need? Recipe: Makes 18 cupcakes 12 ounces butter 6 ounces sugar 9 ounces flour 3 eggs

Answers

Deepak only needs to use 2/3 of the recipe if he only wants to make 2/3 of the amount it produces.

12/3 = 4 ounces of butter per 6 cupcakes
6/3 = 2 ounces of sugar per 6 cupcakes
9/3 = 3 ounces of flour per 6 cupcakes
3/3 = 1 egg per 6 cupcakes

You then need to multiply all of those answers by 2 to get the answer for 2/3 as those are the answers for 1/3.

4x2 = 8 ounces of butter
2x2 = 4 ounces of sugar
3x2 = 6 ounces of flour
1x2 = 2 eggs
