What are the solutions of x2 + 10x + 16 = 0?
1. write the equation in standard form.
x2 + 10x + 16 = 0
(x + 2)(x + 8) = 0
x+2 = 0 or x+8 = 0
x= and x =

If 2(a^2+b^2)=(a+b)^2 then, > a+b=0, > ab=0, > a=b, > 2a=b

Circle a has a diameter of 7 inches, a circumference of 21.98 inches, and an area of 38.465 square inches. the diameter of circle b is 6 inches, the circumference is 18.84 inches, and the area is 28.26 square inches. part a: using the formula for circumference, solve for the value of pi for each circle. (4 points) part b: use the formula for area and solve for the value of pi for each circle. (4 points)
