Hello :D

Answer:

<u><em>X=-4</em></u>

<u><em>The answer should have a negative sign.</em></u>

Step-by-step explanation:

Distributive property

   ↓

A(B+C)=AB+AC

Expand the form.

2(x-2)-4x=-2x+4

-2x+4=12

Then, you subtract by 4 both sides of an equation.

-2x+4-4=12-4

Subtract the numbers from left to right.

12-4=8

-2x=8

Divide by -2 both sides of an equation.

\frac{-2x}{-2}=\frac{8}{-2}

Finally, you divide by the numbers from left to right to find the answer.

8\div-2=-4

X=-4 is the correct answer.

Hope this helps you!

Have a wonderful day! :D

Answer:

x = -4

Step-by-step explanation:

Distribute 2 inside the parentheses

2\times x = 2x\\ 2\times2=4\\ 2x+4 - 4

Combine like terms

-4x + 2x = -2x + 4 = 12

Subtract 4 from both sides

-2x = 8

x = -4

Step-by-step explanation:

as with any division of a multiplication of various factors, we can always simplify by reducing the factors in the top and the bottom of the same base.

in the same way we can for example do

36×2⁶×3⁴×5² / 4×2⁵×3³×5²

and deal with every exponent base individually creating

9×2¹×3¹×5⁰ = 9×2×3

we can do with variable based exponents.

24a⁸b⁸c⁶ / 8a⁷b³c³ =

= 3a¹b⁵c³

you know, when we divide, we simply subtract exponents.

8-7, 8-3, 6-3

and the constants are simply divided 24/8 = 3

Give a big-o estimate for the number of operations (where an operation is an addition or a multiplication) used in this segment
Marianna [84]
We have a "rectangular" double loop, meaning that both loops go to completion.
So there are 3*4=12 executions of t:=t+ij.

Assuming two operatiions per execution of the innermost loop, (i.e. ignoring the implied additions in increment of subscripts), we have 12*2=24 operations in all.

Here the number of operations (+ or *) is exactly known (=24). 

Big-O estimates are used for cases with a varying scale of operations, governed by a variable (usually n) to indicate the sensitivity of the number of operations relative to a change in the size of n.

Here we do not have a scale, nor n is defined.  The number of operations is constant and known at 24.   So a variable is required to find the big-O estimate.
