Question: Evaluate the expression for the given value of the variable. | − 4b − 8 | + ∣ − 1 − b² | + 2b³; b = − 2

-11

Step-by-step explanation:

What we are required to do here is to find the value of the expression assuming that variable b = -2.

Bear in mind that, where you see the symbol "| ... |", enclosing a set of terms, the absolute value after performing whatever function with the enclosed terms is what is to be found. This means, after performing the operation, if you have a negative value, simply ignore the negative sign.

Now let's evaluate at b = -2

|- 4b - 8| + ∣-1 - b²| + 2b³ (given)

|- 4(-2) - 8| + ∣-1 - (-2)²| + 2(-2)³ (substitution)

|8 - 8| + ∣-1 - 4| + 2(-8)

|0| + ∣-5| - 16

0 + 5 - 16 (absolute value of -5 = 5)

= -11

step-by-step explanation: the answer is 27. first multiply .32 by 25 which equals 8. then add 8 to 25 which gives you 33. then you subtract that from 6 since she gave 6 to her brother.

,, add !

other answer is correct. i had used the radius of the radius somehow. a website:
