Me answer number 3plz explain how you do it

6 miles

Step-by-step explanation:

The benchmark number are 0 1/2 and 1, so we round to the nearest whole number or 1/2 number

3 1/8 miles is close to 3  

2 5/6 miles is close to 3  (5 is very close to 6  to 5/6 is close to 1)

We are adding

3 1/8 + 2 5/6

3 + 3 = 6

About 6 miles

answer: i wpould go with c

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
