2.56 is the width of the garden

step-by-step explanation:

1st integer x

2nd integer x+1

3rd integer x+2

4th integer x+3

x+x+1 +x+2+x+3 =74

combine like terms

4x+6 = 74

subtract 6 from each side

4x = 68

x = 17

the integers are 17,18,19,20

you should go to the second answerthey explain it very well, give me a like

answer is b  

20

hope you get this one right.
