babymother [125]

Answer:

Step-by-step explanation:

First, let's add the 20 dogs and 15 cats together to find the total number of animals adopted

20 + 15 = 35 animals adopted

We cand do 35 ÷ 200 to find how much of a percent 35 is of 500

35 / 500 = 0.07

Multiply this number by 100 to get a percent

0.07 × 100% = 7%

7% of the animals

Condense the following logarithm: 5log_4(a) - 6log_4(b)

grin007 [14]

Hi there! We are given the expression:

$\large \boxed{5 log_{4}(a) - 6 log_{4}(b) }$

To condense or simplify the following logarithm. You have to remember these properties:

Properties - Logarithm

$\large{ log_{b}(a)^{n} = n log_{b}(a) } \\ \large{ log_{b}(a) - log_{b}(c) = log_{b}( \frac{a}{c} ) }$

These two properties are what we need for our problem. Therefore,

$\large{ log_{4}(a)^{5} - log_{4}(b)^{6} }$

We use the log_b(a)^n = nlog_b(a) property to convert in the form above. Next, we use the second property.

$\large{ log_{4}( \frac{ {a}^{5} }{ {b}^{6} } ) }$

Answer

log base 4 of (a^5/b^6) is our simplifed form.

Any questions can be asked through comment as I may reply soon. Thanks for using Brainly! Have a good day and happy learning! :)

What is 4x^2-1/ (x+4) (2x-1) simplified

Nadusha1986 [10]

Answer:

Step-by-step explanation:

$\frac{4x^2 - 1}{(x+4)(2x-1)} = \frac{(2x)^2 - (1)^2}{(x+4)(2x-1)}$

$=\frac{(2x-1)(2x+1)}{(x+4)(2x-1)}\\\\=\frac{2x+1}{x+4}$
