Make x the subject means you need to solve for x

y = ax^2 solve for x

divide both side by a

y/a = ax^2/a

simplify
y/a =  x^2
so
x = square root (y/a)

vlabodo [156]
Circle since diameter
area=pir^2
d/2=r
15/2=7.5=r
area=pi7.5^2
area=pi56.25
1/4 of that
56.25pi times 1/4=14.0625pi

answer is 14.0625pi in^2 or aprox 44.1786375 in^2

\\ \rm\longmapsto 2^{4x+4}=64^{x+2}

\\ \rm\longmapsto 2^{4x+4}=(2^6)^{x+2}

\\ \rm\longmapsto 2^{4x+4}=2^{6(x+2)}

\\ \rm\longmapsto 4x+4=6(x+2)

\\ \rm\longmapsto 4x+4=6x+12

\\ \rm\longmapsto 4-12=6x-4x

\\ \rm\longmapsto -8=2x

\\ \rm\longmapsto x=\dfrac{-8}{2}

\\ \rm\longmapsto x=-4
