Answer:
Answer is x=328 .
Step-by-step explanation:
solution= (4x-16)^1/2=36
squaring both sides we get
4x-16=129
4x=1296+16
x=(1296+16)/4
x=328 .
Answer:
8%
Step-by-step explanation:
0.36/4.50=0.08=8%
Hello,
For a given perimeter (P) there are an infinity of Area (A)
Let's say x the length, and y the wide of the rectangle
P=2(x+y)
A=xy
k=x-y >=0
As (x+y)²-4xy=(x-y)²: A²-4P=k² or P=(A²-k²)/4
In primus, you will find a graph (abacus) giving P for a A and k given.
Negative Area or P are excluded.(just remind the first quadrant, A>=0 and P>=0)
So if the equation is 6y<18, you have to get the y alone so you have to do inverse operations.
Since 6 is being multiplied by y, you have to divide the whole equation by 6. You are left with y<3, which is the answer. Do you understand?
