Perimeter is legnth +legnth + width + width or
P=2L+2W
L=2W
subsitute L=2W for L in P=2L+2W
P=2(2W)+2W
P=4W+2W
P=6W
we know that Perimiter=30 so
30=6W
divide both sides by 6
5=Width
subsitute W=5 for W in L=2W
L=2(5)
L=10
to check
10=2(10)+2(5)
30=20+10
30=30
checks
Legnght=10
Width=5
The value of x is determined by an equation where both sides are equal.
Ok I got 32.995 I’m not sure what place you need to round to so I kept that throughout my solving process. I’m not too sure if this is right but here is the work that I did in the picture. I didn’t show the distance formula as I used an online calculator lol.
Q^3 = 27
q^3 = 3^3
Therefore, q = 3
