Since they lose three yards on the first play, we can write -3 for the start. Next, since they gain six, we add 6 to get -3+6= net yards
Answer:
9 inches of rainfall produces the maximum number of gnats.
Step-by-step explanation:
Given : 
To Find :How many inches of rainfall produces the maximum number of gnats?
Solution:

G(x) =The number of gnats in millions.
x denotes the length of rainfall
To Find the maximum length find the mid point of zeroes .Since parabolas are symmetrical, the x value of the max falls 1/2 way between the zeros.



So, x = 0 , x= 18
Now Formula of midpoint : 


Hence 9 inches of rainfall produces the maximum number of gnats.
Answer:
A= 1/2d -1/2N
Step-by-step explanation:
If wy is congruent to xy, then from w to y is equal to the distance between x and y. According to the figure, both distances are 3m-4 each. Therefore the perimeter is the sum of the three sides, namely:

Solving for m:
