In the election for class president, there were two candidates, joel and sean. joel got 60% of the votes, which was 38 votes more than sean. find the total number of votes cast.

190.

Step-by-step explanation:

Let x represent total number of votes.

We have been given that Joel got 60% of the votes, which was 38 votes more than Sean.

60% of total votes:  

Since Joel got 60% of total votes, so Sean got 40% of total votes that is  

Since Joel got 38 votes more than Sean, so we can represent this information in an equation as:

Therefore, the total number of votes cast is 190.

step-by-step explanation:

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
