Answer:
22.45
Step-by-step explanation:
7 = -16t2 + 16t + 3
7 = t2 + 3
7 -3 = t2 + 3 - 3
4 = t2
square root of 4 = square root of t2
2 = t
2 seconds
<span>Starting with 500 and creating a pattern that subtracts 4 from each number would give us an expression of x = n - 4 where x is the next number in progression and n is the current number. Using this expression we get the following sequence out to 5 numbers. 500, (500-4)=496, (496-4)=492, (492-4)=488, (488-4)=484. The final sequence is 500, 496, 492, 488, 484.</span>
The area of a rectangle is A = length x width
You would therefore get 36 = length x width
Then, since length is 6 feet longer than twice its width,
you would get length = 2(width) + 6
You would therefore end up with 36 = (2w + 6) x w
solving for width you find it to be 3 feet
Plugging that back in to the area formula, you get 12 feet to be the length.
