What is the first step in simplifying the expression?

B. Multiply the binomial by 3.  

Step-by-step explanation:

We have been given an expression: . We are asked to determine the first step in simplifying the expression.

Since we know that the order of operations is also known as PEMDAS, where,  

P= Parenthesis,

E= Exponents,

M= Multiplication,  

D = Division,

A =Addition,

S = Subtraction.

According the order of operations we will distribute 3 to binomial or multiply the binomial by 3. Therefore, option B is the correct choice.

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional

answer: it is 8

step-by-step explanation:

you know why its 8
