We know that if they say students they mean both boys and girls so we add 11 and 10 to make 21 and since its, (COACH,) and then student we do 1:21 and not 21:1!
By equating both quadratic equations, Brian can determine the point of intersection of both equations. Upon graphing he was able to identify that both share the same vertex but of opposite opening. Based on this, he can say that both equations are equations of parabolas with same vertex but open on different directions.

Answer:
8 is your answer for x
Step-by-step explanation:
Note that this is an equilateral triangle, meaning that all of the sides are congruent. This means that all the angel measurements are congruent.
First, divide 180 with 3 (3 because there are 3 angles)
180/3 = 60
Each angle must equal 60. You are solving for x. Set the expression with x as the variable equal to 60
7x + 4 = 60
Isolate the x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS. First, subtract 4 from both sides.
7x + 4 (-4) = 60 (-4)
7x = 60 - 4
7x = 56
Next, divide 7 from both sides.
(7x)/7 = (56)/7
x = 56/7
x = 8
8 is your answer for x.
