Let the side of each side of photo is a inch.
So area of photo = (side)^2 =

But as given area of photo is 9 square inch.
So


So side of photo is 3 inch.

Jake travel to the coffee shop by bike with speed of
is
and when bike got a flat so Jake walked 
How to find the speed by biking and walking ?

Answer:
Step-by-step explanation:
let the eq. of circle be x²+y²+2gx+2fy+c=0 ...(1)
∵ it passes through (-1,2),(4,2),(-3,4)
∴ (-1)²+2²-2g+4f+c=0
-2g+4f+c=-5 ...(2)
4²+2²+8g+4f+c=0
8g+4f+c=-20 ...(3)
(-3)²+4²-6g+8f+c=0
-6g+8f+c=-25 ...(4)
(3)-(2) gives
10 g=15
2g=3
g=3/2
(3)-(4) gives
14 g-4f=5
14×(3/2)-4f=5
-4f=5-21=-16
f=4
from (2)
-2(3/2)+4×4+c=-5
-3+16+c=-5
c=-5-13
c=-18
so eq. of circle is
x²+y²+2(3/2)x+2(4)y-18=0
x²+y²+3x+8y-18=0
Well look at the resources available, you can study or if you have a study guide, use it and try to get a good night rest and wake up on time and try your best and don’t stress out or you can just wing it and not do nothing and just take the test
