<h3><u>The value of x is equal to 1.</u></h3><h3><u>6(x + 2) = 20x - 2</u></h3>

<em><u>Distributive property.</u></em>

6x + 12 = 20x - 2

<em><u>Add 2 to both sides.</u></em>

6x + 14 = 20x

<em><u>Subtract 16x from both sides.</u></em>

14 = 14x

<em><u>Divide both sides by x.</u></em>

x = 1

What is the value of (tan 65° - tan 35°) / 1 + tan 65°tan 35°?<br> 0<br> 0 V3/3
goldenfox [79]

Answer:

\frac{ \sqrt{3} }{3}

Step-by-step explanation:

We know that tangent angle addition formula is

\tan(a   -  b)  =  \frac{ \tan(a)  -  \tan(b) }{1 +  \tan(a)  \tan(b) }

This is in form already. Based on the value, a is 65 and b is 35 so let just subtract that

\tan(65 - 35)  =  \tan(30)

W e know that tan 30 is

\tan(30)  =  \frac{ \sin(30) }{ \cos(30) }  =  \frac{ \frac{1}{2} }{ \frac{ \sqrt{3} }{2} }  =  \frac{1}{ \sqrt{3} }  =  \frac{ \sqrt{3} }{3}

Andru [333]
D=days

29.99d + 5= 124.96

29.99d= 124.96-5

29.99d= 119.96

D= 119.96/29.99

D= 4

Angela rent the car for 4 days. Hope this helps!

Can someone describe the lower bounds theorem?
prisoha [69]

The lower bound is the smallest value that would round up to the estimated value. A quick way to calculate upper and lower bands is to halve the degree of accuracy specified, then add this to the rounded value for the upper bound and subtract it from the rounded value for the lower bound.
