James bought a cake that weighs pounds. how many ounces does the cake weigh? show your work. (5 points) [16 ounces = 1 pound] part b: a running tap dispenses 0.15 gallons of water every second. how many pints of water is dispensed after 20 seconds? show your work. (5 points) [1 gallon = 4 quarts, 1 quart = 2 pints]

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

lol 2
