-11

Step-by-step explanation:

| -4b-8| + |-1-b^2| +2b^3   where b = -2

| -4(-2)-8| + |-1-(-2)^2| +2(-2)^3

Exponents first

| -4(-2)-8| + |-1-4| +2(-8)

Then inside the absolute values

| 8-8| + |-5| +2(-8)

| 0| + |-5| +2(-8)

0+5 -16

-11

answer: 4 meters

step-by-step explanation: to you understand 2/3 better you can do 1 divided by 3 = . then multiply that by the 2 which is .66666666666666667 then you would do 6 x .66666666666666667 which is 4.      

hope this .
