Mathematics

Answer:

16

Step-by-step explanation:

The quadratic equation –3 = –x2 + 2x must first be rewritten in standard form:  

x^2 - 2x - 3 = 0

or:

1x^2 - 2x - 3 = 0

The coefficients a, b and c are thus {1, -2, -3}, and therefore the discriminant, b^2 - 4ac, is

(-2)^2 - 4(1)(-3), or 4 + 12 = 16

Just need some help with math
V125BC [204]
Each pie/circle has 10 sections. there is 3 whole sections so you would do 10x3 is equal to 30.

then, there’s a fourth pie that has one unshaded section. so, that would be only 9. add the 30 and 9 and you would get 39.

so, for the one fraction, you would get 39/10.

for the mixed number, you get 3 9/10 because 10 goes into 39 3 times and then you have 9 left over.
