Answer:
L=25; W=17
Step-by-step explanation:
1. Create an equation
L+L+W+W=P -> (2w-9)+(2w-9)+(w)+(w)=84
2. Solve for W
a) Collect like terms
(2w-9)+(2w-9)+(w)+(w)=84 -> 6w-18=84
b) Move constant to the right
6w-18=84 -> 6w=102
c) Divide by 6
6w=102 -> w=17
3. Now plug in W to the L
2w-9=L -> 2(17)-9=L
a) Multiply
2x17=34 -> 34-9=L
b) Subtract
34-9=25 -> 25=L
Answer:
uh imma say 8 sides im not 100% sure but try it and if wrong then i will change my answer
Step-by-step explanation:
The value of equation when n = 3 is 50
<em><u>Solution:</u></em>
<em><u>Given equation is:</u></em>
We have to find the value of equation when n = 3
By plugging in n = 3 in given equation we can find the value of given equation
<em><u>Substitute n = 3 in given equation</u></em>
Thus the value of equation when n = 3 is 50
