Answer:

Step-by-step explanation:

2(2x + 1) = (2)(2x) + (2)(1) = 4x + 2 → A

<em>used distributive property</em>

2(2x + 1) = 2(1 + 2x) → B

<em>used commutative property</em>

2(2x + 1) = (2x + 1) + (2x + 1) = 2x + 1 + 2x + 1 → D

2(2x + 1) = 4x + 2 = x + x + x + x + 1 + 1 → E

Solve 3 over x minus 3 equals the quantity of x over x minus 3, minus three-halves. for x and determine if the solution is extra

astraxan [27]

$\frac{3}{x} -3 = \frac{x}{x} - \frac{3}{2}$
$3 -3x = x - \frac{3x}{2}$
$-6x -2x -x = 6$
$-9x=6$
$9x=6$
$x= \frac{6}{9}= \frac{2}{3}$

4 over k = 3 yay more math i destroyed one page in the midst of babysitting

Bad White [126]

The value of k should equal to 4/3. You can multiply k on each side to get 4=3k and divide by 3 to get 4/3=k. Another approach is to reciprocate the RHS and LHS of the equation to get k/4=1/3, and then multiply by 4 on each side to get k=4/3.

Let U={b, c, d, e, f, g, h} and A={b, f, g, h}. Use the roster method to write the set A'

podryga [215]

The roster method to write the set A' will be {c, d, e}.

Sets are groups of clearly specified components. The number of items in a finite set is denoted by a curly bracket.

Let U = {b, c, d, e, f, g, h} and A = {b, f, g, h}.

The roster method to write the set A' will be given as,

A' = U - A

A' = {b, c, d, e, f, g, h} - {b, f, g, h}

A' = {c, d, e}

The roster method to write the set A' will be {c, d, e}.
