X = number of correct answers
Y = number of incorrect answers
School A has 174 points and school B has 102 points.
A = 174
B = 102
School A has the same number of correct and incorrect answers during the final round.
A = 174 + 10X - 6Y
School B gives no incorrect answers and the same number of correct answers as school A.
B = 102 + 10X
The contest ends with the two schools tied.
Score = 174 + 10X - 6Y = 102 + 10X
174 + 10X - 6Y = 102 + 10X

Answer:
(x-5)(x+6)=0
Step-by-step explanation:
hehe i doing the smae unit rn.
if a=1 (which it does do ac factoring)
you need two numbers that multiply to -30 and add to 1. those numbers are 5 and -6.
substitute 1x for -5x + 6x.
group the numbers into pairs and find their gcf's
x(x-5) 6(x-5)
since the parenthesis r the same yo only need one. Now you need to put x and 6 in a parenthesis.
FINAL: (x-5)(x+6) hope this helps
