Hey guys so im in a little trouble i need some help please. I got 3 i just need 4,5,6,7,8,9,10 please and also i need step by step and there might be a reward

4. x= -6

5. x= 7

6. x= -18

7. x= 8

8. x= 7

I'll do 9 and 10 in a separate answer

Step-by-step explanation:

4. Multiplying a negative with another negative always equals a positive, so replace x with -6, multiply -6 and -3 and you'll get 18.

5. To make it simple, think "what minus 3 equals 11?" So in this case, multiplying 2 by 7 would = 14, and that minus 3 is 11.

6. Divide a negative by a positive to get a negative answer. -9 + 6 = -3, but first we have to get 9. So since the fraction is x divided by 2, you'd replace x with -18 to get -9.

7. -3 x 8 is -24, + 11 is -13.

8. What minus 7 equals 21? 28. So replace x with 7. (7 x 4 = 28), subtract 7 from 28, and then you'll have 21.

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.  

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
