Simplify the expression and then evaluate it for the given value of the variable:

Natasha_Volkova [10]

Answer:

-5x+21
22

Step-by-step explanation:

There are no factors outside the parentheses that need to be distributed, so the parentheses can be simply dropped:

6 -2x +15 -3x

The terms can be rearranged to put like terms next to each other:

-2x -3x +6 +15

and the like terms can be combined.

-5x +21 . . . . simplified expression

Put the value of x where x is, then do the arithmetic.

-5(-0.2) +21 = 1 +21 = 22

The product of some negative number and 4 less than twice that number is 336. Find the number.

Dennis_Churaev [7]

Let the number be 'x'

Since, the product of number and 4 less than twice that number is 336.

$x \times [(2 \times x) -4] = 336$

$x[2x -4] = 336$

$2x^2 -4x- 336=0$

$x^2-2x-168=0$

Now, we will split the middle term, we get

$x^2-14x+12x-168=0$

$x(x-14)+12(x-14)=0$

$(x-14)(x+12)=0$

So, $(x-14)=0 or (x+12)=0$

So, x = 14 or x = -12

Therefore, the negative number is '-12'.
