The surface area of a sphere is 4r^2pi, so dividing 100 by 4pi gives a result of 25/pi. Taking the square root and rationalizing the denominator, we have 5sqrt(pi)/pi as the radius of the sphere.
This is what i got:
-x-20=6x+1
Answer:
1 + (11-4)^2 +3x5

Answer: She messed up in Step 1
She first should of tried to factor it first. There she can see that 3 and -11 work together in order to get (x+3)(x-11)
x= -3 and x=11
