What is the coefficient of x2 in the expansion of(x+2)3

Pachacha [2.7K]

First expand:

$(x+2)(x+2)(x+2)$

$(x^2+4x+4)(x+2)$

$(x^3+2x^2+4x^2+8x+4x+8)$

Now combine like terms:

$x^3+6x^2+12x+8$

A coefficient is a number that is in front of an x. The number in front of the x squared term is 6.

So the answer is 6.

If there are 48 boys and 64 girls and the teachers decided to put them each in in equal rows only boys or girls will be in each

german

Answer: 16

Step-by-step explanation:

The question seeks to know the largest number of people that can sit in each row.

To answer this, find the Highest Common Factor of the numbers 48 and 64.

Factors of 48 ⇒ 1, 2, 3, 4, 6, 8, 12, 16, 24 and 48

Factors of 64 ⇒ 1, 2, 4, 8, 16, 32 and 64

Because the teacher wants the rows to be equal with either only boys or only girls sitting in them, the highest number of people that can sit in a row will be 16.

There will be 7 rows in total.

Boys ⇒ 48/ 16 = 3 rows

Girls ⇒ 64/16 = 4 rows
