Step-by-step explanation:

Step 1: Recognize you can put 1:12 into a fraction along with 36 students with 'x' as number of teachers when you have 36 students

Step 2: Set the 2 fraction equal to each other

Step 3: Cross multiple and solve for 'x'

Therefore there are 3 teachers present when there are 36 students in the class

the answer is b

step-by-step explanation:

10a^3+277a^2-132a-792

step-by-step explanation:

(2a+11)(5a-12)(foil)

=10a^2-24a+55a-132 =10a^2+31a-132

(10a^2+31a-132)(a+6)

=10a^3+60a^2+31a^2+186a^2-132a-792 =10a^3+277a^2-132a-792
