What is Euclid's fifth postulate

Nataly [62]

Answer:

Euclid fifth postulate gives information regarding parallelism of lines.Euclid's fifth postulate states If a straight which falls on two straight lines makes interior angle on the same side of it.And if sum those two interior angles is less than 180° ,then two straight will not be parallel which means they if they produced indefinitely they will surely meet on the side where some of interior angles is less than 180°.

This postulate is more complex as compared to other four postulates.It says that two parallel lines never meet.This postulate is also known as parallel postulate.

What does 1/8 times 1/2 equal

JulsSmile [24]

The answer is 1/16.

When it comes to fractions, it's quite simple! If you can multiply, you can do this!
Simply write the the top number over the bottom so it looks normal. Multiply straight across. 1x1 is 1, and 8x2 is 16. Don't do anything else! It's 1 over 16 OR 1/16

Extended Problems, Extraneous Solutions

diamong [38]

Answer:

1a. 2 is the solution

1b. -3 is because square root of 1 doesn't equal -1.

1c.-3

Step-by-step explanation:

1.

$(x + 2 = \sqrt{3x + 10}$

Square both sides

$(x + 2) {}^{2} = 3x + 10$

Remeber perfect square Rule

$(x + y) {}^{2} = {x}^{2} + 2xy + {y}^{2}$

So now we got

$x {}^{2} + 4x + 4 = 3x + 10$

${x}^{2} + x + 4 = 10$

${x}^{2} + x - 6 = 0$

Factor into binomial.

$(x + 3)(x - 2) = 0$

So our solution is 3 or 2. However, let's check our work.

$- 3 + 2 = \sqrt{3( - 3) + 10}$

$- 1 = \sqrt{1}$

However square root of 1 is 1. It could be 1 but in Math, <em>We</em><em> </em><em>only</em><em> </em><em>take</em><em> </em><em>the</em><em> </em><em>principal</em><em> </em><em>square</em><em> </em><em>root</em><em> </em><em>which</em><em> </em><em>is</em><em> </em><em> </em><em>positive</em><em> </em><em>always</em><em>.</em><em> </em><em>So</em><em> </em><em>-3</em><em> </em><em>isn't</em><em> </em><em>a</em><em> </em><em>solution</em><em>.</em>

<em>So</em><em> </em><em>let</em><em> </em><em>try</em><em> </em><em>2</em><em>.</em>

<em> $2 + 2 = \sqrt{3(2) + 10} = 4 = \sqrt{16} = 4 = 4$ </em>

<em>So</em><em> </em><em>this</em><em> </em><em>is</em><em> </em><em>indeed</em><em> </em><em>the</em><em> </em><em>solution</em><em>.</em>

<em>Make</em><em> </em><em>up</em><em> </em><em>equation</em><em> </em><em>for</em><em> </em><em>2</em><em> </em><em>and</em><em> </em><em>3</em><em>.</em><em> </em><em>Ask</em><em> </em><em>me</em><em> </em><em>if</em><em> </em><em>you</em><em> </em><em>need</em><em> </em><em>help</em><em>.</em>
