The difference of two trinomials is x2 − 10x + 2. If one of the trinomials is 3x2 − 11x − 4, then which expression could be the

12345 [234]

Answer:

$4x^2-21x-2$

Step-by-step explanation:

Given that:

Difference of two trinomials is $x^2 - 10x + 2$

One of the two trinomials is $3x^2 - 11x - 4$

To find:

The other trinomial = ?

Four options are:

$2x2 - x - 2 \\2x2 + x + 6 \\4x2 + 21x + 6\\ 4x2 - 21x - 2$

Solution:

Let the two trinomials be A and B.

Given A - B = $x^2 - 10x + 2$

B = $3x^2 - 11x - 4$

We have to find the other trinomial A.

A - B = $x^2 - 10x + 2$

A - ( $3x^2 - 11x - 4$ ) = $x^2 - 10x + 2$

$\Rightarrow$ A = $x^2 - 10x + 2$ + ( $3x^2 - 11x - 4$ )

$\Rightarrow$ A = $4x^2-21x-2$

So, the correct answer is $4x^2-21x-2$ .

Burka [1]

Answer:

David took 16 oranges.

Step-by-step explanation:

We are given the following in the question:

Total number of oranges = 48

Oranges rotten =

$\dfrac{1}{3}$

Number of oranges rotten =

$\dfrac{1}{3}\times 48\\\\=16$

There were 16 rotten oranges.

Number of good oranges left =

$= 48-16\\=32$

These are equally divided among Ben and David.

Number of oranges each Ben and David get =

$\dfrac{32}{2} = 16$

Thus, David took 16 oranges.
