35-(x+7) 
= 35-35x-245
= -35x -210
i’m not 100% sure on this because you used square brackets but i think this is the correct answer
        
                    
             
        
        
        
That equals 4,810. Make sure to have a placeholder when you multiply

Answer :
<h3>
 
 <u>
 =1048576 ways </u>
 a student can answer the questions on the test if the student answers every question.</h3>
Step-by-step explanation:
Given that a multiple-choice test contains 10 questions and there are 4 possible answers for each question.
∴ Answers=4 options for each question.
<h3>
To find how many ways  a student can answer the given questions on the test if the student answers every question :</h3>
Solving this by product rule
Product rule :
<u>If one event can occur in m ways and a second event occur in n ways, the number of ways of two events can occur in sequence is then m.n</u>
From the given the event of choosing the answer of each question having 4 options is given by
The 1st event of picking the answer of the 1st question=4 ,
 2nd event of picking the answer of the 2nd question=4 , 
3rd event of picking the answer of the 3rd question=4 
,....,
10th event of picking the answer of the 10th question=4.
It can be written as  by using the product rule 



<h3>∴ there are 1048576 ways a student can answer the questions on the test if the student answers every question.</h3>
