D. because each day =34 and it is 5days 5×34= 170 so the answer is more than 4 gallons
8 is the missing number
Let’s say x is 2,
3(2)+8=14
8(2)-2=14
Perimeter = (length+width) x 2
Let w units be the width of the rectangle.
Length of the rectangle = 2w
Perimeter:
(2w+w) x 2 = 60
(3w)2 = 60
6w = 60
w = 10
Area:
2(10) x 10
= 20 x 10
= 200 units
