The answer is a.
x^2 -10x+25 = x*x-2*5*x+5*5 => (x-5)(x-5)
Volume of a sphere is V=(4/3)pi r^3
300(.1337)=(4/3)pi r^3
solve for r
r= 2.12 ft
Answer:
16,19
Step-by-step explanation:

Hope this helps!
Answer:Answer is D
Step-by-step explanation:
It CORRECT
Answer:
y = -5
Step-by-step explanation:
-10(-1/2y + (-7/2)) + 7y = -25
Let's first of all expand the bracket to get;
5y + 35 + 7y = -25
12y + 35 = -25
12y = -25 - 35
12y = -60
y = -60/12
y = -5
