5. a square pizza has an area of 121 square inches. find the length of one side of
the pizza. draw and label.

6. the area of a circle is 49 square units. the formula for the area of a circle is
tr2. what is the radius of the circle?

faster, im not sure why but i know it is faster

i need more details sorry

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0
