Me asap pls extra points for all of these give me answers pls !

1. 3 terms, coefficients: (-20), 5, (-7)

2. 3 terms, coefficients: 8, (-20), (-10)

3. -The factors in the term 5 are 5 and 1.

   -The factors in the term 6a are 6 and a.

   -The factors in the term 11b are 11 and b.

4. -The factors in the term 13m are 13 and m.

   -The factors in the term (-2)n are (-2) and n.

5. The expression represents the total amount that Erin pays at the store.

6. The expression represents the number of bees that visits the plant.

Step-by-step explanation:

1. We have the polynomial -20+5p-7z.

The terms of a polynomial are separated by + and - (This signs aren't in parentheses or brackets, in a fraction or in a root.)

Then,

-20+5p-7z, this polynomial has 3 terms.

A polynomial is an expression of the form: , where each real number is called coefficient.

Then the coefficients of -20+5p-7z are (-20), 5 and (-7).

2. We have now 8x-20y-10

This polynomial has 3 terms. And the coefficients are 8, (-20) and (-10).

3. 5+6a+11b

A factor is one part of a product.

In this polynomial we have 3 terms.

-The factors in the term 5 are 5 and 1. (because 5.(1)=5

-The factors in the term 6a are 6 and a.

-The factors in the term 11b are 11 and b.

4. 13m-2n

In this polynomial we have two terms.

-The factors in the term 13m are 13 and m.

-The factors in the term -2n=(-2)n are (-2) and n.

5. We have the expression 0.99c+0.79a

Each cucumber cost $0.99 and c represents the number of cucumbers that Erin is going to buy.

Each apple cost $0.79 and a represents the number of apples that Erin is going to buy.

Then 0.99c+0.79a represents the total amount that Erin is going to pay at store.

6. We have now the expression 500t

In this expression t is the number of years the plant is alive.

And the numbers of bees that visit a plant is 500 times the number of years the plant is alive.

Then 500t is the number of bees that visit the plant.

the expected value of the random variable : 0, 1 and 2

step-by-step explanation:

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake
