Answer:
Option 4
Step-by-step explanation:
Equating given length and width to the area :
- 8x(5x) = 490
- 40x² = 490
- x² = 490/40
- x² = 12.25
- x = 3.5
Finding the dimensions :
- length = 8x = 8(3.5) = 28 units
- width = 5x = 5(3.5) = 17.5 units
Answer is X is equal to 9
Answer:
x=4/3
Step-by-step explanation:
3x=5-1
3x=4
x=4/3
I would say the answer is false. There can be some cases where you may not need to do so, but not always.
