Mr. Grizzard spent $640 to stay in a hotel for four nights. Each night he spent x dollars on the hotel room as well as a $15 parking fee per day. The equation below represents the total amount, in dollars, that Mr. Grizzard spent on his hotel. 4(x + 15) = 640

How much money did the hotel room cost for one night, excluding the parking fee?

A.
$145.00

B.
$156.25

C.
$163.75

D.
$175.00

126 maybe. sorry

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

i think its a.

hope this
