Simplify 3[2^3 + (4-2)^3 - (6-2)^2]

Ivahew [28]

Answer:

$\boxed{0}$

Step-by-step explanation:

$3(2^3 + (4 - 2)^3 - (6 - 2)^2)$

$= 3(2^3 + 2^3 - 4^2)$

$= 3(2.2^3 - (2^2)^2)$

$= 3(2^4 - 2^4)$

$= 3(0)$

$= 0$

Samuel used the distributive property to simplify the expression -6(-2 - 10x) - 7x and came up with 53x - 12 which is incorrect.

Komok [63]

Answer:

He messed up the signs, most likely by multiplying incorrectly. It should be 53x+12.

Step-by-step explanation:

You begin by multiplying both -2 and -10x by -6.

Remember a negative times a negative makes a positive.

-6(-2-10x)

12+60x

Then you need to combine like terms which are 60x and -7x

60x-7x

53x

So that means the final answer will be

53x+12
