Answer:
Let the breadth is x, then the length is 3x.
<u>The area is:</u>
<u>The breadth is decreased by 2 m: </u>
<u>The length is increased by 4m: </u>
<u>The area is now:</u>
- (x - 2)(3x + 4) = 3x² - 1/3(3x²)
- 3x² + 4x - 6x - 8 = 2x²
- x² - 2x - 8 = 0
- x² - 2x + 1 = 9
- (x - 1)² = 3²
- x - 1 = 3
- x = 4
The breadth was 4 m and the length 12 m
Answer:
y = 444mmm + 333
Step-by-step explanation:
let total marbles = y
putting mmm marbles in 444 bags we have the total in the bags to be 444mmm
but there are 333 marbles left that didnt fit in the bags giving us (+333)
adding them both together
therefore the total marbles will be 444mmm + 333
