Which options could be the next step in simplifying this expression?

1 answer:

7 0

<span>In adding, subtracting, multiplying and dividing numbers, always remember this rule: PMDAS (or parenthesis, multiply, divide, add, subtract). The P in PMDAS must come first. We must use an order of operations. In the problem given, (18 + 23) + 7, they must be added. However you have a parenthesis that has the numbers 18 and 23. You will add 18 and 23 first and then you will get 41. And so the answer is 41 + 7, letter B. </span>

Solve the following: 2(5x-3)

Otrada [13]

Answer:

The vale of x is 3/5.

Step-by-step explanation:

First you have to expand out :

$2(5x - 3)$

$= 2(5x) - 2(3)$

$= 10x - 6$

Next you have to solve it by adding 6 to both sides :

Let expression = 0,

$10x - 6 = 0$

$10x - 6 + 6 = 0 + 6$

$10x = 6$

$x = \frac{6}{10}$

$x = \frac{3}{5}$

Which expression is equivalent to log3(x + 4)?

solmaris [256]

ANSWER

The third option is the correct answer

$log3(x + 4) = log(3) + log(x + 4)$

EXPLANATION

The expression given to us is

$log3(x + 4) = log(3) + log(x + 4)$

This logarithmic expression is of the form

$log(A \times B)$

So we use the multiplication law of logarithm which is given by

$log(A \times B) = log( A ) + log( B )$

We therefore set

$A = 3$

$B = x + 4$

The given expression now becomes,

$log3(x + 4) = log(3) + log(x + 4)$
