I guess since you have the correct answer there that you need to know how to get it. Start by rewriting that exponent as a radical. It would look like this: . The first step is to undo that square root by squaring both sides. That will give you this:
. Next we have to undo that cubing by taking the cubed root of both sides, leaving us with this:
. We add 8 to both sides to get 8x = 24 and x = 3.

Answer:
The missing side length is 27 in
Step-by-step explanation:
see the attached figure
we know that
1 ft= 12 in
step 1
Convert ft to in
2 ft=2*12=24 in
Note ----> the given measure is 13 in instead of 13 ft
step 2
Find the missing side length
The perimeter of a quadrilateral is the sum of its four side lengths
Let
x------> the missing side length
P=x+24+13+15
P=79 in
so
79=x+24+13+15
x=79-52=27 in
The missing side length is 27 in
