The greatest common factor is the biggest thing that they all share... If we look at it they all have 4 as their coefficients so you can take that out but they also have a squared so you can take that out too so the GCF if 4a squared... but No x because one of them doesn't have it... all of them have to have it in common.

<h3>Answer:  a = -3 and b = 5</h3>

=================================================

Work Shown:

Multiply top and bottom by \sqrt{2} to rationalize the denominator

\frac{10-\sqrt{18}}{\sqrt{2}}\\\\\frac{\sqrt{2}(10-\sqrt{18})}{\sqrt{2}*\sqrt{2}}\\\\\frac{\sqrt{2}*10-\sqrt{2}*\sqrt{18}}{\sqrt{2*2}}\\\\\frac{\sqrt{2}*10-\sqrt{2*18}}{\sqrt{4}}\\\\\frac{10\sqrt{2}-\sqrt{36}}{2}\\\\\frac{10\sqrt{2}-6}{2}\\\\\frac{-6+10\sqrt{2}}{2}\\\\\frac{2(-3+5\sqrt{2})}{2}\\\\-3+5\sqrt{2}\\\\

We end up with something in the form a+b\sqrt{2} where a = -3 and b = 5

Could 13.5 cm, 8.0 cm, and 3.5 cm be the side lengths of a triangle?
Sergio039 [100]
The answer is no, it couldn't be because the side lengths do not adhere to the triangle inequality theorem. which states that the sum of the side lengths of any 2 sides of a triangle must exceed the length of the third side

3.5+8>13.5 Is not correct.

Does y = 3/4 x + 6 and y = -3/4 x + 5 have one solution
Mumz [18]

Answer:

yes

Step-by-step explanation:

Given the 2 equations

y = \frac{3}{4} x + 6 → (1)

y = - \frac{3}{4} x + 5 → (2)

Substitute y = \frac{3}{4} x + 6 into (2)

\frac{3}{4} x + 6 = - \frac{3}{4} x + 5 ( add \frac{3}{4} to both sides )

\frac{3}{2} x + 6 = 5 ( subtract 6 from both sides )

\frac{3}{2} x = - 1 ( divide both sides by \frac{3}{2} )

x = \frac{-1}{\frac{3}{2} } = - \frac{2}{3} ← one solution
