Answer:
steps
1) 14/28 to convert to a percent you have to first divide the numerator from the demoninator and then you multiply by 100 and you get get %50 (you could had known bc 14 is half of 28)
2) 5/28 do the same thing as the first step and get %17.85

Hello from MrBillDoesMath!
Answer:
31a. 2 real roots
31b 2 complex roots
Discussion:
31a.
2x^2 + 3x - 6 = 0
Using standard quadratic notation, the above equation has a = 2, b = 3 and c = -6. The discriminant is given by b^2 - 4ac, which is
3^2 - 4*2*(-6) = 9 + 48 = 57 > 0, so the quadratic has 2 real roots
31b.
The equation is equivalent to 16x^2 + 10x +3 = 0. Its discriminant is
10^2 - 4 * (16) * (3) = 100 - 192 = -92 so this equation has two complex roots

Hi there!
Combining th' like terms of the expressions.
(7y² - 3y) + (8y² - 8y)
7y² - 3y + 8y² - 8y
(7y² + 8y²) + (-3y - 8y)
15y² - 11y
Hence,
Option [ 1. ] - 15y² - 11y is Correct
~ Hope it helps!
I got 7x+4 because you distribute then add the X's and the whole numbers together.
