The answer should be 'b ≤ 7' because b should equal or be less than 7 bags.
I hope this helps; please mark me brainliest!
Have a great day!
4x = y
2x^2 - y = 0
2x^2 - 4x = 0
2x(x - 2) = 0
2x = 0 or x - 2 = 0
x = 0 or x = 2
y = 4(0) or y = 4(2)
y = 0 or y = 8
Therefore, solution set is {(0, 0), (2, 8)}
Formula
Area = L*w
Hint : To find the area of a rectangle , multiply the length times the width
I hope that's help !
