What are two different way of factoring -3x-9? Select all that apply
Ghella [55]

Options:

A. –3(x + 3)

B. 3(x + 3)

C. 3(–x – 3)

D. –3(x – 3)

Answer:

A and C

Step-by-step explanation:

Given

-3x - 9

Required

Factorize

The options are not given; So, I'll answer on a general term

-3x - 9

Express -9 as -3 * 3

-3x - 9 = -3x - 3 * 3

Then factorize 3 out of the expression as:

-3x - 9 = 3(-x - 3)

Another way is to factor -3 out of the expression as:

-3x - 9 = -3x - 3 * 3

-3x - 9 = -3(x + 3)

PLEASE HELPPPP ! 16^x=64^x+4
Vladimir [108]

Answer:

x = -12

Step-by-step explanation:

Set logs up on both sides-

log 16^x = log 64^x+4

The variable goes behind because of the exponent log <em>property</em> (exponents are permitted to go behind the log to multiply)-

x * log 16 = x + 4 * log 64

Divide both logs out-

log 64/log 16 = 1.5

Simplify-

x = x+4(1.5)

1.5x + 6 = x

Remove 1.5-

1 - 1.5 = -.5x

Simplify-

-.5x = 6

Divide both sides-

6/-.5x = -12

Hence, the answer would be -12
