A pool contains 300 L of water. It empties at a rate of 6.4 L/min. Write
an equation to determine how long it
will be until the pool contains only
60 L of water. Then, solve.

Someone help please

Step-by-step explanation:

(300-60)/6,4=37,5

answer: translate the circles so they share a common center point and dilate circle y by a scale factor of 3.

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
