A(100-62)/100=17100 multiply both sides by 100
a(100-62)=1710000 combine like terms on left side
38a=1710000 divide both sides by 38
a=45000
So the arena has a total of 45000 seats.
Answer:
76
Step-by-step explanation:
recall that for a quadratic equation in the form
ax² + bx + c = 0, the discriminant is given by
discriminant, D = b²- 4ac
we are given the following:
-6x² + 2x + 3 = 0,
comparing this with the general equation above, it is clear that,
a = -6, b = 2 and c = 3,
substituting these into our equation for discriminant:
D = b²- 4ac
= 2² - 4(-6)(3)
= 4 + 72
= 76
