The standard form of -36/34
shepuryov [24]

Assuming that you mean "simplified form", we have to cancel every common divisor of both numerator and denumerator.

36 is factored as 2^2\cdot 3^2

34 is factored as 2\cdot 17

So, the two numbers only have a factor 2 in common, meaning that the simplified form of this fraction is

-\dfrac{18}{17}

If -12-4(-2x)= 4 then what is x?
11111nata11111 [884]

Answer:

\boxed{\boxed{\sf x=2}}

Step-by-step explanation:

\sf -12-4\left(-2x\right)=\:4

First, let's remove parentheses:

\sf -12-4\times -2x=4

Simplify, multiply, 4 * -2x = -8x:

\sf -12-(-8x)=4

** Apply rule: - ( -a )= a

\sf 12+8x=4

Now, let's regroup terms

\sf 8x-12=4

Add 12 to both sides:

\sf -12+8x+12=4+12

Simplify, 4 + 12= 16

\sf 8x=16

Divide both sides by 8:

\sf \cfrac{8x}{8}=\cfrac{16}{8}

\sf x=2
