Write the expression as a cube of a monomial: 0.008y^21

0.2y^7

Step-by-step explanation:

you start of with 0.008y^21 and you want to find the cube

0.2 is the cube of 0.008 now all that is left is to figure out y

since we know that when we exponent an exponent exp

(2^3)^6 = 2^18 how i know this is 6x3 = 18

so 21/3 = 7

answer is 0.2y^7

it's d.

step-by-step explanation:

because: -1(4x + 1y) +2 (1x-3y) distribute each number into the parenthesis.

then you would get: -4x - 1y + 2x -6y combine like terms

and get: 2x -7y

hope my answer has you if not then i'm sorry.

associative property hopes this ! : )
