Answer:
Length = 17 cm
Width = 8 cm
Step-by-step explanation:
Let the length be x cm
Therefore, Width = (x - 9) cm
Perimeter of rectangle = 2(l +w)
50 = 2[x + (x - 9)]
50/2 = 2x - 9
25 = 2x - 9
25+ 9 = 2x
2x = 34
x = 34/2
x = 17 cm
x - 9 = 17 - 9 = 8 cm
Therefore,
Length = 17 cm
Width = 8 cm
Thus, the dimensions of the rectangle are 17 cm and 8 cm.

in 1st case first multiply
then add both the product
9.01 * 10^3 in scientific notation is 9.01 * 10^3.
I got this answer by moving the decimal so there is a non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent of the 10. If the decimal is binge move to the right, the exponent will be negative, but if the decimal is being moved to the left the exponent will be positive.
I hope this helps! :>
