Answer: 5 weeks
Explanation:
Jess starts with $22 and saves $5 per week, Rosie has $10 and saves $8 per week.
In order to find an equal amount of money between the two girls is by finding a common denominator.
Jess- 22, 27, 32, 37, 42
Rosie- 10, 18, 26, 34, 42
Since we found that they can both end up with $42, after a certain amount of weeks have passed, now you’ll want to count how many numbers are in each row to find the amount of weeks it took to get to an equal amount
Answer:
x=8
Step-by-step explanation:
(2x + 1)² = x² + (2x - 1)² = x² + (2x - 1)(2x - 1)
(2x + 1)(2x + 1) = x² + 4x²-2x-2x+1
4x²+2x+2x+1 = 5x²-4x+1
4x²+4x+1 = 5x²-4x+1
0= 5x²-4x²-4x-4x+1-1
0= x²-8x
x²-8x=0
x²=8x
x=8
Answer:
