Remember revese distributeive
ab+ac=a(b+c)
factor out
(a^2)(x+3)+(-4)(x+3)
undistribute (like rreverse distribute where (x+3)=a)
(a^2-4)(x+3)
we can stil factor a^2-4 into a^2-2^2=(a-2)(a+2)
(a-2)(a+2)(x+3)
the value of x is certainly equal to 3
Answer:
Area = pi x radius squared
the radius is 2.39 so that's squared that is 5.7121pi
