Answer by JKismyhusbandbae: Radius is 12 and perimeter is six times this, i.e. 72.
To answer this problem we have to use two different variables. For example...
L = Length
W = Width
So we know that the definition of perimeter is
L + L + W + W (or all the sides added up)
Now we also know that The Length is 4 times longer than the width.
So we can write 4W to replace the L
So in the given equation we set up Replace every L with 4W
4W + 4W + W + W = 60 meters
now group our W's
10W = 60 divide both sides by 10 to get W to be alone
÷10 = ÷10 It cancels on the left side and we solve on the right side.
W = 6
So now that we know what the width equals we can find what the length equals .
Remember this?
4W = L (plug in 6 for W)
4(6) = L
So L = 24
Our dimensions of this rectangle are length 24, width 6.
Good Luck! :)

1. Correct answer is a (since when you are not given the n values, it is implied that the first value is 1).
3. Correct answer is a (a(n)=-3+4(1-1)=-3).
7. The pattern is to reduce the previous value by 4, thus the 12th term of the sequence is -24 (a(n)=20 - 4(n-1)=20 - 4(12-1)=-24).
8. Missing term is 26 (32+20=52; 52/2=26).
10. Pattern is 625/1=625; 625/5=125; 125/5=25; 25/5=5, thus. the 10th term is 1/3125 (answer a).
I am assuming when you write 27x5 u mean "27 times x to the power of 5".
therefore, your answer is 9x3-11x2-7x
