<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)
