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
The answer i got was 1/4+x. the only thing close to that is b.
hope this helps.
the answer to the first question would be 
the answer to the second question will be 
To solve this you will do 90.27 * .15 which is 13.5405 and if you round that it will be 13.50.
