Step-by-step explanation:

$\frac{x + 4}{3 {x}^{2} - 12x - 96} = \frac{x + 4}{3( {x}^{2} - 4x - 32) } = \frac{x + 4}{3(x - 8)(x + 4)}$

$= \frac{1}{3(x - 8)} = \frac{1}{3x - 24}$

The relationship between a bacteria population p, in thousands, and time d, in days, since it was measured to be 1,000 can be re

Assoli18 [71]

d = log₂p represents a logarithmic function, The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

<h3>What is an exponential function?</h3>

An exponential function is in the form:

y = abˣ

Where a is the initial value of y and b is the multiplication factor.

Let p represent the bacteria population in thousand after d days.

Since each day, the bacteria population grows by a factor of 2, hence:

$p=2^d$

Hence, d = log₂p represents a logarithmic function

The expression log₂(10) tells us when the population reaches 10,000 and the equation 7 = log₂(128) tells us that the population reaches 128,000 in 7 days.

Answer:

A. AA, SAS, SSS

Step-by-step explanation:

<u>This is the option A</u>

If two triangles have two of their angles equal, the triangles are similar.

SAS

If two triangles have two pairs of sides in the same ratio and the included angles are also equal, then the triangles are similar.

SSS

If two triangles have three pairs of sides in the same ratio, then the triangles are similar.

<u>Other elements mentioned:</u>

HL- this is a congruence but not similarity
ASA- same as above
AAS - neither similarity nor congruence rule
