1). -16÷-4
2). simplify 4(x+6)+2(x+3)
3). 5x^3y+4x^2y^2+x-17 find the degree
4). (x+7)(x+1)
5). 4c-11=10c-5

1. -16/-4 = 4

2. for this we have to distribute throughout the parenthesis. This means that the 4 is multiplied by both the x and the 6. and the same for the 2 being multiplied by both the x and the 3. This will simplify to

Now we have to combine like terms. This gives us the answer

3. The degree is the largest exponent in the equation so in the equation

The largest exponent is 3, so that would be the degree

4. For this one we must distribute the x to both the x and 1. Then we must do the same with the 7. Lastly, we must combine like terms.

Lets begin with the x,

and now 7

Now we have to combine like terms

So the answer is

5. For this one we must solve for c. In order to do this, we must combine like terms and then isolate c.

First, we must subtract 4c from each side as well and add 5 to each side. This will leave us with

Now we can divide each side by 6, so that c will be alone. And we will be left with as our answer

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25

16 is the coefficient

hope this
