Answer:
if the discriminant < 0 no solution
if = 0 then one solution
if > 0 then two solutions
start from the first one and calculate b^2-4ac
the first one is x^2 + 4x +4 = 0
a is the factor next to x^2 (1 in this case)
b is the factor next to x (4 in this case)
c is the number without any x (4 in this case)
so the discriminant is 4^2 - 4*(1)*4 = 16-16 = 0 = one solution

Answer:
58240
Step-by-step explanation:
Given
Represent cost with c and size with s.
So, we have:
when
Required
Find c when s = 1820
For direct variation, we have:
Write as equation:
when , we have:
So, the equation is:
When s = 1820
