Answer:
<4=146
<5=34
<6=146
<7=34

Answer:
-2265
Step-by-step explanation:
First, we replace x with 20.
![f(20)=-5*20^2-13*20-5](https://tex.z-dn.net/?f=f%2820%29%3D-5%2A20%5E2-13%2A20-5)
Then, we evaluate.
The * stands for multiplication.
![f(20)=-5*20^2-13*20-5\\-5*400-260-5\\-2000-260-5\\-2265](https://tex.z-dn.net/?f=f%2820%29%3D-5%2A20%5E2-13%2A20-5%5C%5C-5%2A400-260-5%5C%5C-2000-260-5%5C%5C-2265)
We are given the statement that states that multiplication sentences can have factors in different order. In this case, in multiplication, the order of the factors does not matter because it still comes up with the equal product.
