What are the potential solutions of log4x+log4(x+6)=2?
lions [1.4K]

The potential solutions of log_4x+log_4(x+6)=2 are 2 and -8.

<h3>Properties of Logarithms</h3>

From the properties of logarithms, you can rewrite logarithmic expressions.

The main properties are:

  • Product Rule for Logarithms - log_{b}(a*c)=log_{b}a+log_{b}c
  • Quotient Rule for Logarithms - log_{b}(\frac{a}{c} )=log_{b}a-log_{b}c
  • Power Rule for Logarithms - log_{b}(a^c)=c*log_{b}a

The exercise asks the potential solutions for  log_4x+log_4(x+6)=2. In this expression you can apply the Product Rule for Logarithms.

                                  log_4x+log_4(x+6)=2\\ \\ x*(x+6)=4^2\\ \\ x^2+6x=16\\ \\ x^2+6x-16=0

Now you should solve the quadratic equation.

 

 Δ=b^2-4ac=36-4*1*(-16)=36+64=100. Thus, x will be x_{1,\:2}=\frac{-6\pm \:\sqrt{100} }{2\cdot \:1}=\frac{-6\pm \:10}{2}. Then:

x_1=\frac{-6+10}{2}=\frac{4}{2} =2\\ \\ \:x_2=\frac{-6-10}{2}=\frac{-16}{2} =-8

The potential solutions  are 2 and -8.

A cube shaped terrarium has a volume of 27/64 cubic feet. What is the length of its sides?
Dafna1 [17]
A cube is a 3 dimensional object with 6 square faces. All its sides are the same length, there fore the volume is equal to s^3 where s is the side length.

s^3 =  \frac{27}{64}

To solve for s, take the cube root of both sides.

\sqrt[3]{s^3}= \sqrt[3]{ \frac{27}{64} }

s= \frac{3}{4} feet

Answer:

B. FOIL

Step-by-step explanation:

FOIL stands for Firsts, Outsides, Insides, and Lasts

This is a mnemonic to help you to remember how to multiply two binomials

From the image, we can see that the on the right side of the equals,

(x)(-5x^2) is the product of the <u>firsts</u> of the binomials

(x)(x) is the product of the <u>outsides</u> of the binomials

(-2)(-5x^2) is the product of the <u>insides</u> of the binomials

(-2)(x) is the product of the<u> lasts</u> of the binomials.
