Which expression can be added to the right side of the equal sign to form an equation? 30+2* 1. 3(2+3) 2. 7(2+1) 3. 6(3+7) 4. 5(4+1)

we will use

this rule in order of operation

P: Parenthesis

E: Exponent

M: Multiplication

D: Division

A: Addition

S: Subtraction

we are given

30+2*10....

we can simplify it

now, we will check option and verify whether it is equal to 50

option-a:

3(2+3)

=3*5

=15

so, this is FALSE

option-b:

7(2+1)

=7*3

=21

so, this is FALSE

option-c:

6(3+7)

=6*10

=60

so, this is FALSE

option-d:

5(4+1)

=5*5

=25

so, this is FALSE

step-by-step explanation:

descending order means to order the polynomials from the term with the largest exponent to the term with the smallest exponent.  

therefore, the correct answer is d.
