Please help 50 points!<br> Simplify the expressed

LenKa [72]

Answer:

Step-by-step explanation:

$\frac{x^{2} -x-12}{x+4} * \frac{2x^{2}-32 }{x^{2} -8x+16}$ rewrite as multiplication

$\frac{x^{2} +3x-4x-12}{x+4} * \frac{2(x^{2}-16) }{x^{2} -8x+16}$ look to factor

$\frac{x(x+3)-4(x+3)}{x+4} * \frac{2(x-4)(x+4) }{(x-4)^{2}}$ , difference of 2 squares and perfect square

$\frac{(x+3)(x-4)}{x+4} * \frac{2(x-4)(x+4) }{(x-4)^{2}}$ , finish factoring and simplify

Help me please I am confused with the question about the 3 digit number ?

vazorg [7]

Answer:

900

Step-by-step explanation:

3-digit natural numbers are whole numbers that range from 100 to 999 (3-digit because there are three numbers)

- 999 whole numbers from 1 to 999 (counting from 1, 2, 3, 4...897, 898, 899)

- 1 to 99 are 2-digit numbers, so you do not count them

999 - 99 = 900

there are 900 3-digit natural numbers!

comment or message me if you are still confused!
