what is 6xy . 12 over x 100 over 6
Answers
X2 + -6xy + -12 = 0
Reorder the terms:
-12 + X2 + -6xy = 0
Solving
-12 + X2 + -6xy = 0
Solving for variable 'X'.
Move all terms containing X to the left, all other terms to the right.
Add '12' to each side of the equation.
-12 + X2 + 12 + -6xy = 0 + 12
Reorder the terms:
-12 + 12 + X2 + -6xy = 0 + 12
Combine like terms: -12 + 12 = 0
0 + X2 + -6xy = 0 + 12
X2 + -6xy = 0 + 12
Combine like terms: 0 + 12 = 12
X2 + -6xy = 12
Add '6xy' to each side of the equation.
X2 + -6xy + 6xy = 12 + 6xy
Combine like terms: -6xy + 6xy = 0
X2 + 0 = 12 + 6xy
X2 = 12 + 6xy
Simplifying
X2 = 12 + 6xy
Reorder the terms:
-12 + X2 + -6xy = 12 + 6xy + -12 + -6xy
Reorder the terms:
-12 + X2 + -6xy = 12 + -12 + 6xy + -6xy
Combine like terms: 12 + -12 = 0
-12 + X2 + -6xy = 0 + 6xy + -6xy
-12 + X2 + -6xy = 6xy + -6xy
Combine like terms: 6xy + -6xy = 0
-12 + X2 + -6xy = 0

Suppose you need to put a fence around a rectangular garden that has a perimeter of 64ft. The width is 12ft less than the length. Find the width and length of the garden.
Answers
Answer:
x=length
x-12=width
you techinally have to count 2 lengths and 2 widths.
2x + 2x - 24= 64
4x = 88
x = 22
so the length is 22 and the width is 10

what is representation of root?The principal nth root of a is written as n√a , where n is a positive integer greater than or equal to 2. In the radical expression, n is called the index of the radical.
A radical symbol √ is used to represent a square root; the number or expression included within the radical symbol, designated by the letter a below, is known as the radicand.
We have that [tex]77 ^ {1/10}[/tex].
Now, if we have given that √4 we can write it as [tex]\sqrt[2]{4}[/tex]
Again, if we have [tex]7^{1/3}[/tex] we can write it as [tex]\sqrt[3]{7}[/tex]
Similarly we can write 77^1/10 as [tex]\sqrt[10]{77}[/tex]

–5(1 – 5x) + 5(–8x - 2) = -4x – 8x
Answers
Answer: x = -5
-------------------------------------------------------------------------------------------------------------
Step-by-step explanation:
Let's solve your equation step-by-step.
−5(1−5x)+5(−8x−2)=−4x−8x
-------------------------------------------------------------------------------------------------------------
Step 1: Simplify both sides of the equation.
−5(1−5x)+5(−8x−2)=−4x−8x
(−5)(1)+(−5)(−5x)+(5)(−8x)+(5)(−2)=−4x+−8x(Distribute)
−5+25x+−40x+−10=−4x+−8x
(25x+−40x)+(−5+−10)=(−4x+−8x)(Combine Like Terms)
−15x+−15=−12x
−15x−15=−12x
-------------------------------------------------------------------------------------------------------------
Step 2: Add 12x to both sides.
−15x−15+12x=−12x+12x
−3x−15=0
-------------------------------------------------------------------------------------------------------------
Step 3: Add 15 to both sides.
−3x−15+15=0+15
−3x=15
-------------------------------------------------------------------------------------------------------------
Step 4: Divide both sides by -3.
−3x /−3 = 15/ −3
x=−5
