to find the average you need to multiply depending on the sittuation
Hey there!
To start, you must use the distance formula which is 
.
x1 and x2 are the x coordinates of the points (it does not matter which one you assign to be x1 and x2) and y1 and y2 are the y coordinates (also does not matter which one you assign to be y1 and y2).
Now, set up your formula and simplify:
= 
≈ 25.0799
Answer:
17%
Step-by-step explanation:
If 30% of the school is girls and 10% wear glasses, that means that at least 3% of the school wears glasses. (10 percent of 30%) If 70% of the school is boys and 20% of boys wear glasses, at least 14% of the school wears glasses. (20% of 70%) If you add both of those numbers together it adds up to 17%.
-4x^2-5(x+3)+x^2 :
-4x^2-5x-15+x^2
-3x^2- 5x -15
Find the cubic root of the first term ( numbers)
∛49 = 3.659
∛81 = 4.326
∛121 = 4.946
∛ 343 = 7
Because ∛343 is the only whole number answer ( no decimal places) the last answer is the correct one.
