There are two closed containers and four balls just fit in each container. each ball has a diameter of 60mm. which container had the smallest surface area? you must show your working using mm. your final line should say either a is smaller or b is smaller. mathswatch

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

2, 2, 2 or -4, 20, 29

step-by-step explanation:

there is two ways you can do it.

can you post the graph?
