Hey uh i know i keep asking questions but the unit i am doing is a bit tricky for me, Here is the problems: Also I only need 1 - 4 and #9 I thank all of you for helping me out!

1st awnser 60min= 3600

a tenis ball can lauch 7200tenis balls in 2 hours

2 hours = 7200

2

2 awnser: 5L:25Seconds=1L:5seconds

In 50 seconds there will be 10L of water

In 45 We will have to subtract 1L because we are exceeding 5 seconds and in 5 seconds 1L of water comes out

10L-1L=9L

There will be 9L of water

this one is for the second one for B The seconds answer is 300 seconds for 60 liters.

3.There are 640 kilocalories in the 2 cups of dog food

the awnser for 4 will be $1.70

The awnser for number 9 will be car A

f(x) = x^3 -2x^2 -3x

x( x^2 -2x-3)

x( x^2 +x -3x -3)

x( x(x+1) -3(x+1))

x( x-3)( x+1)

so zeroes are 0, 3,-1

its (2) option

can you make your screen more see able?

then i might be able to .
