Steps to solve:

9(d - 93) = -36d

~Distribute

9d - 837 = -36d

~Subtract 9d to both sides

-837 = -45d

~Divide -45 to both sides

18.6 = d

Best of Luck!

Can someone please help out with this. I know I did the problem incorrectly.
Sloan [31]

Answer:

Correct answer:  C. -20

Step-by-step explanation:

If  (x-3) is a polynomial factor it means that the polynomial value at point 3 is zero.

H(3) = 3 · 3³ - 2 · 3² + 3k - 3 = 0 ⇒  81 - 18 + 3k - 3 = 0 ⇒ 3k + 60 = 0

3k = - 60  ⇒  k = - 60/ 3 = - 20

k = - 20

Find the value of X.<br><br> Please show/explain work, and sorry if it’s hard to read
aliya0001 [1]

Answer:

x = 100°

Explanation:

The polygon has 6 sides, meaning it's a hexagon. In the picture you can see the following steps under #1:

(6-2) x 180° = 4 x 180 = 720°

720 is the total amount that all the angles should add up to, including the missing number x.

To solve for x add all of the angles up:

120 + 156 + 145 + (x + 9) + x + 90 = 720

520 + 2x = 720 (subtract 520 from both sides)

                 -520

          2x = 200 (divide 200 by 2 to have x on its own)

             x = 100°

To make sure it's correct, plug in the value (100°) for x in the original equation to check the answer:

120 + 156 + 145 + 100 + 9 + 100 + 90 = 720

720 = 720 Correct
