Please help Graphing quadratic functions

Step-by-step explanation:

To find the width, we have to find the distance between (-450, -300) and (450, -300) because those are the endpoints of the arch. Since the y-coordinates of the 2 points are equal, we just have to subtract their x values, which is 450 - (-450) = 900.

To find the width, we have to find the distance between (0,0) (the maximum) and (0, -300) (the lowest point). This is 0 - (-300) = 300. Hope this helps!

the answer is 510

step-by-step explanation:

15 • 13 = 195

15 • 12 = 180

15 • 5 = 75

12 • 5 = 60

195 + 180 = 375

375 + 75 = 450

450 + 60 = 510

24

step-by-step explanation:

if it takes 8 pounds to make 12 divide 12 by 8 and you get 1.5, 1.5 x 16 = 24
