Answer:
Answer a) length = x - 2
Answer b) area = 6x - 12
Answer c) perimeter = 2x + 8
Step-by-step explanation:
Any rectangle has a width and a length.
Given is width = 6 cm
The length is at this moment unknown, but we know something important. The length of this rectangle is 2 less than the diagonal. Lets call the length of the diagonal as x.
So although we do not actually know how long the diagonal is, we can still "pretend" it's value to be x. That is perfectly allowed, isn't it?
That way, the length = x-2. ( because that info was also given). Just don't worry to leave x in your answer :-).
Answer a) length = x - 2
So length = x - 2 and width = 6
The rest is easy!
area = width * length
area = 6 * (x - 2)
Answer b) area = 6x - 12
perimeter = 2 * width + ( 2 * length )
perimeter = 2 * 6 + ( 2 * (x - 2) )
perimeter = 12 + ( 2x - 4 )
perimeter = 2x + 8
Answer c) perimeter = 2x + 8

Answer:
no, Andre ran at a sperm of 8km/hr while jada ran at 9km/hr you can find that by Andre going 2km in 15 minutes which turns to hours by multiplying by 4/4 to get 8/60 which 60 minutes is 1 hour then jada multiply by 3/3 which would be 9/60
