Answer:
-2
Step-by-step explanation:
Slope of the line
Factor the following:
x^2 + 9 x + 8
The factors of 8 that sum to 9 are 8 and 1. So, x^2 + 9 x + 8 = (x + 8) (x + 1):
Answer: (x + 8) (x + 1)
Answer: a square root of a number x is a number y such that y² = x; in other words, a number y whose square is x. For example, 4 and −4 are square roots of 16, because 4² = ² = 16
The square of any number is always a positive number, so every number has two square roots, one of a positive value, and one of a negative value. For example, both 2 and -2 are square roots of 4.
All you have to do is multiply the 80 adults by the cost of an adult tickets wich is 80 x 8=640 and then calculate the cost of children's tickets which is 20 x 20=400 then add 400 to 640 400+640 = 1040 then subtract the amount the school donated from that which is 1040-125= 915 and 915 is your answer
hope this helps! :)
