Tito purchased sandwiches and a gallon of milk for himself and his friends. Each sandwich cost $9. The gallon of milk cost $6. The total cost of the meal was $33. the equation for x, the number of sandwiches that Tito purchased? *

answer SHOULD be 3 sandwiches

Step-by-step explanation:

33-6=27÷9=3

9x + 6 = 33; 3

Step-by-step explanation:

9x + 6 represents the number of sandwiches and gallon of milk Tito purchased. 33 represents the total cost of the sandwiches and milk. Using this equation, we can solve to find x (the number of sandwiches purchased). Therefore, x = 3.

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
