Answer:
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: [tex]a_{n}x^n+...+a_{2}x^2+a_{1}x+a_{0}[/tex], where each real number [tex]a_{i}[/tex] 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.
