LOTS OF POINTS <br> Simplify the expression by factoring, showing the steps in your work
julia-pushkina [17]

Answer:

\frac{3x+7}{4x+1}

Step-by-step explanation:

\frac{12x^2+31x+7}{16x^2+8x+1}

First you factor 12x^2+31x+7:

=\left(12x^2+3x\right)+\left(28x+7\right)

Then you factor out 3x from 12x^2+3x:

12x^2+3x

=12xx+3x

=3\cdot \:4xx+3x

=3x\left(4x+1\right)

Then you factor out 7 from 28x+7:

28x+7

=7\cdot \:4x+7

=7\left(4x+1\right)

=3x\left(4x+1\right)+7\left(4x+1\right)

Factor out common term 4x+1:

=\left(4x+1\right)\left(3x+7\right)

\frac{\left(4x+1\right)\left(3x+7\right)}{16x^2+8x+1}

Factor 16x^2+8x+1:

=4^2x^2+8x+1

=4^2x^2+8x+1^2

=\left(4x\right)^2+8x+1^2

=\left(4x\right)^2+2\cdot \:4x\cdot \:1+1^2

Use the perfect square formula:

=\left(4x+1\right)^2

\frac{\left(4x+1\right)\left(3x+7\right)}{\left(4x+1\right)^2}

Cancel out common factor 4x+1:

=\frac{3x+7}{4x+1}

In an arithmetic sequence {an}, if a1 = 5 and d = 3, find a72. A) 216 B) 218 C) 221 D) 223
Phoenix [80]

The arithmetic sequence with the given condition is determined recursively by

\begin{cases}a_1=5\\a_n=a_{n-1}+3&\text{for }n>1\end{cases}

So we have

a_2=a_1+3

a_3=a_2+3=a_1+3(2)

a_4=a_3+3=a_1+3(3)

and so on with the general pattern

a_n=a_1+3(n-1)

This means the 72nd term in the sequence is

a_{72}=a_1+3(72-1)=5+3(71)=218

so the answer is B.

Steven conjectures that for |x|&gt;5, it is true that x^3&gt;125. Is his conjecture correct? Why or why not?
vredina [299]

Conjectures are conclusions formed from evidences. Steven's conjecture that: x^3 > 125 is true because: x > 5 or x > -5 for |x| > 5

Given that:

|x| > 5

Split the inequality as follows:

x > 5 or x > -5

Take the cube of both sides

x^3 > 5^3 or x^3 > -5^3

Evaluate all exponents

x^3 > 125 or x^3 > -125

Steven's conjecture that: x^3 > 125 is true because:

x > 5 or x > -5 for |x| > 5
