Answer:

5c^2+2cd-2d^2-15

Step-by-step explanation:

To solve this problem, we must add up all the side values.

Our equation for the perimeter will look like:

side1+side2+side3+side4=perimeter

Now lets plug in our values for our sides and solve:

4c^2+4cd+12+c^2-d^2+1+3cd+4d^2-30-5d^2-5cd+2=perimeter

Now lets combine like terms:

5c^2+2cd-2d^2-15

So this is our perimeter!

Hope this helps! :3

Hi there! The answer is A) x = 3 or x = 6

2 {x}^{2}  - 18x + 36 = 0
Divide by 2.

{x}^{2}  - 9x + 18 = 0
Factor.

(x - 3)(x - 6) = 0
Use the rule AB = 0 gives A = 0 or B = 0

x - 3 = 0 \:  \: or \:  \: x - 6 = 0 \\ x = 3 \:  \:   \:  \:  \:  \:  \:  \:  \: or \:  \: x = 6

The answer is A) x = 3 or x = 6
