(3x-1) (x²-3x+4)

Multiply the brackets together

3x(x^2-3x+4)

3x^3-9x^2+12x

-1(x^2-3x+4)

-x^2+3x-4

3x^3-9x^2+12x -x^2+3x-4

3x^3-9x^2-x^2+12x+3x-4 (just rearranging)

3x^3-10x^2+15x-4

Answer: 3x^3-10x^2+15x-4

20 points!! Type the correct answer in the box. Use numerals instead of words. What value of n makes the equation true? -1/5n+7=
vredina [299]

Hey there! :)

Answer:

\huge\boxed{n = 25}

-1/5n + 7 = 2

Start by subtracting 7 from both sides:

-1/5n + 7 - (7) = 2 - (7)

-1/5n = -5

Multiply both sides by the reciprocal of -1/5, or -5.

(-5) · (-1/5n) = (-5) · (-5)

n = 25

Lena estimated the height of a desk to be 38 inches. The actual height is 41 inches.
Leno4ka [110]

Answer:

7.3%

Step-by-step explanation:

First you have to find out what 38 out of 41 is as a percentage

This is 92.68%

so now we have to do

100.00 - 92.68 this is 7.32

But you said round to the nearest tenth so it would actually be rounded down to 7.3%
