Mike has 57 action figures. alex has 186 action figures. which is the best estimate of the number of action figures together?

We are given

Mike has action figures =57

Alex has action figures =186

We are given the best estimate of the number of action figures together

so, we can add them to find total action figures

so,

total action figures =Mike has action figures+Alex has action figures

now, we can plug values

and we get

total action figures =186+57

total action figures =243

so,

the best estimate of the number of action figures together is 243Answer

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
