Red : Blue :
3 8
We have 40 blue marbles
Multiply 8 by what to get 40
40/8 =5
So we need to multiply by 5
Red : Blue :
3*5 8*5
15 40
There are 15 red marbles
Answer:
3m+m^2
Step-by-step explanation:
Step-by-step explanation:
We will use pythagoras' Theorem for this question

where c is the longest side (in this case, the diagonal)
a and b are the 2nd and 3rd longest side (interchangeable)
given a = 10.6, b = 16.8,

125 miles per hour is equal to 201.168 kilometers per hour.
It's the one second below the question because it does not have two outcomes for x. For example in a relation x could result in y = 2 or y = -2.
Hope this helps! :)
