Simplify (4−b)(5b2+5b−4)

15b^2-5b^3+24b-16

Step-by-step explanation:

(4-b)(5b^2+5b-4)

Open the brackets

20b^2+20b-16-5b^3-5b^2+4b

Collect like terms

20b^2-5b^2-5b^3+20b+4b-16

15b^2-5b^3+24b-16

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|

step-by-step explanation:

because 1/3 is a fraction. we can tell because there is a divisor symbol between the 1 and the 3. if we were to add 2 fractions together, we would add the numerators, which is the number on top, but not the denominators, which is the number on the bottom

1/3+1/3=2/3

hope this !
