The answer is : 5 .
Step by step solution:
Let the width of the rectangle be x.
Width : x
Length : x + 2
x + x + 2 + x + x +2 = 24
4x + 4 = 24
4x = 24-4
4x = 20
x= 20/4
x=5
2,684,735 = 2,700,000 to the nearest hundred thousand
B=41 that would be the answer
The quadratic formula is -b + or - the square root of b squared - 4 times the a value and c value over 2a. So the roots would be -1.354249 and -6.645751. I believe these are the roots.
Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the 10. If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.
Answer: 9.8 × 10 (4 squared)
