Hi!
Let's find the square root of 9/36.
First, find the square root of 9.
To do that, factorize it.
9/3 = 3
3/3 = 1
3 * 3 = 9
The square root of 9 is 3.
Now find the square root of 36.
36/2 = 18
18/2 = 9
9/3 = 3
3/3 = 1
2 * 2 * 3 * 3 = 36
You could also write this as...
2 * 3 * 2 * 3 = 36
Solve part of it and you get...
6 * 6 = 36
The square root of 36 is 6.
The answer is 3/6, but simplified it's 1/2.
Hope this helps! :)

Just look for the smallest number out of the three and then the smallest out of the two left, like 10,2,20. 2, 10, 20
-3x + 4y = 12
x - y = 1....x = y + 1
-3(y + 1) + 4y = 12
-3y - 3 + 4y = 12
-3y + 4y = 12 + 3
y = 15
x - y = 1
x - 15 = 1
x = 1 + 15
x = 16
one solution (16,15)
The answer is 4188.79 inches
Answer: A. A=(1000-2w)*w B. 250 feet
C. 125 000 square feet
Step-by-step explanation:
The area of rectangular is A=l*w (1)
From another hand the length of the fence is 2*w+l=1000 (2)
L is not multiplied by 2, because the opposite side of the l is the barn,- we don't need in fence on that side.
Express l from (2):
l=1000-2w
Substitude l in (1) by 1000-2w
A=(1000-2w)*w (3) ( Part A. is done !)
Part B.
To find the width w (Wmax) that corresponds to max of area A we have to dind the roots of equation (1000-2w)w=0 ( we get it from (3))
w1=0 1000-2*w2=0
w2=500
Wmax= (w1+w2)/2=(0+500)/2=250 feet
The width that maximize area A is Wmax=250 feet
Part C. Using (3) and the value of Wmax=250 we can write the following:
A(Wmax)=250*(1000-2*250)=250*500=125 000 square feets
