Answer:

Daniel's Mistake was that she didnt add all the sides

Step-by-step explanation:

She only added the right side of the triangle, and the right and bottom sides of the square. She is missing the left of the triangle, which is another 6x-4, and the left side of the square, which is 12x +3.

Using these sides the answer should look like this,

set up your problem

1) (6x-4)*2 + (12x+3)*2 + (14x+13)

multiply your 2's in

2) (12x-8) + (24x+6) + (14x+13)

simplify

3) 50x + 11 is your answer

Choose one of the factors of 6x^3 + 6
ivanzaharov [21]

Answer: First option is correct.

Step-by-step explanation:

Since we have given that

6x^3+6

Now, by factorising , we get

6x^3+6\\=6(x^3+1)

Now, we use the formula i.e.

a^3+b^3=(a+b)(a^2-ab+b^2)

By using this, we get ,

6(x^3+1)\\=6(x+1)(x^2-x+1)

So,

(x+1) \text{ is the factor of }6x^3+6.
