A plate moves at a sped of 45 mm/yr. How far will the plate move in 100 years?

4,500 millimeters per year.

Step-by-step explanation:

brainliest?

4500 mm or 4.5 m

Step-by-step explanation:

45 mm/yr x 100 yr = 4500 mm = 4.5 m

chase is right because he already been to the swings and he know how far it will be to get there

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
