Answer: biggest no.=27. Smallest number=9

Step-by-step explanation:

Let's take the smallest number as x and the biggest number as 3x since it is 3 times bigger than x.

The sum of these two numbers is 36

3x+x=36

4x=36

X( smallest number)=36/4: 9

While, the biggest number is 3x: 3×9=27

Given:

The expression is $5+4\times 2+6-2\times 2-1$ .

To find:

The position of parentheses inserted in the expression to get the value 19

Step-by-step explanation:

We have,

$5+4\times 2+6-2\times 2-1$

Now,

$(5+4)\times 2+6-2\times 2-1=9\times 2+6-4-1$

$(5+4)\times 2+6-2\times 2-1=18+6-5$

$(5+4)\times 2+6-2\times 2-1=18+1$

$(5+4)\times 2+6-2\times 2-1=19$

There are more ways to apply the parenthesis, but we do not get 19.

$5+4*\left(2+6\right)-2*2-1=32\neq 19$

$5+4*2+\left(6-2\right)*2-1=20\neq 19$

$5+4*2+6-2*\left(2-1\right)=17\neq 19$

And many more possibilities.

Therefore, the expression after inserting the parentheses is $(5+4)\times 2+6-2\times 2-1$ .

(2n^4 - 8 - 3n) - (4n^2 + 7n +4) <br> I have to simplify but don't know how to

Ahat [919]

First remove the parenthes as there is a negtive outside the second parentheses the signs of the terms inside change.

= 2n^4 - 8 - 3n - 4n^2 - 7n - 4

Now simplify like terms

= 2n^4 - 4n^2 - 10n - 12

= 2(n^4 - 2n^2 - 5n - 6)
