Mikel has $20 to spend at the aquarium. The aquarium charges a $10 admission fee.
The aquarium also has special exhibits that cost $4.00 each to view
Which equation can be used to determine the amount of money, y, that Mikel has left if he views x exhibits?

A y=4−10x
B y=4x-10y=4x−10
C y=10x-4y=10x−4
D y=10-4xy=10−4x

no

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
