Answer:
A. -14 B.-57 C.-14 D.-25
(I USED MY BRAIN SO IT MIGHT BE WRONG)
To find the probability, we do 78% to the third power, which is 0.474552 or when rounded 0.475
<1=<2
<3+(<1 or <2)=180
6x+y-4=x-9y+1
5x+10y=5
12x-9y=177
Solve for x and y

The sum of a and b will be the coefficient of the x term of the trinomial. This can be seen below.
(x + a)(x + b)
= x² + bx + ax + ab
= x² + (a+b)x + ab
x is being multiplied by both a and b individually and the products are being added, so sum of a and b appears as the coefficient of x term.
Thus the answer to this question is option C
