How do I solve: 3(x+4)=3

2 answers:

8 0

In order to solve this, start by distributing the 3.

Essentially, we multiplying each value inside the parenthesis by 3, to get:

3x + 12 = 3

Next, subtract 12 on both sides:

3x + 12 - 12 = 3 - 12

12 - 12 = 0
3 - 12 = -9

So:

3x = -9

The last step here is to divide both sides by 3:

3x ÷ 3 = -9 ÷ 3

3 • X ÷ 3 = X
-9 ÷ 3 = -3

So, long story short, X = -3

3x + 12 = 3

(multiply 3 by the variables in the parentheses)

3x + 12 = 3

add 12 to each side

3x = 15

divide each side by 3

X=5

Expanding logarithmic Expression In Exercise,Use the properties of logarithms to rewrite the expression as a sum,difference,or m

ch4aika [34]

Answer:

$\ln x+\frac{1}{3}\ln (x^2+1)$

Step-by-step explanation:

Consider the given expression is

$\ln (x\sqrt[3]{x^2+1})$

We need to rewrite the expression as a sum,difference,or multiple of logarithms.

$\ln (x(x^2+1)^{\frac{1}{3}})$ $[\because \sqrt[n]{x}=x^{\frac{1}{n}}]$

Using the properties of logarithm we get

$\ln x+\ln (x^2+1)^{\frac{1}{3}}$ $[\because \ln (ab)=\ln a+\ln b]$

$\ln x+\frac{1}{3}\ln (x^2+1)$ $[\because \ln (a^b)=b\ln a]$

Therefore, the simplified form of the given expression is $\ln x+\frac{1}{3}\ln (x^2+1)$ .

25=k/5;k=5 what's the answer

SashulF [63]

25=k/5

25/5/5/1

= (25/5)(1/5)

= (5/1)(1/5)

= (5)(1)/(1)(5)

= 5/5

= 1

I hope that's help !

The mystery number is a three-digit number. Its digits are 1, 8, and 4.

dlinn [17]

Answer:

814

Step-by-step explanation:

there has to be a number between 4,8

so either 4 can be at hundred position or 8 can be at hundredth position.

but since 1 comes before 4, then 1 has to be at tens place and 4 has to be at one's place.

so number is 814

galben [10]

Answer:

Step-by-step explanation:

If you are given with the equation of a line. You have to put the value of Y=0 in the equation. At that point the value of x obtained is known as x-intercept.
