Answer:

= 3 (\sqrt{2}  +\sqrt{5})

Step-by-step explanation:

\sqrt{3} (\sqrt{6}*\sqrt{15}  )

When you have to simplify an expression, always try to find a common number, even if it isnt the solution to a problem is always a good strategy.

Here the 3 numbers are multiple of 3. So your first idea should be to do something with sqrt 3

\\ \sqrt{3} (\sqrt{2}\sqrt{3}  +\sqrt{5} \sqrt{3} )\\= \sqrt{3} ((\sqrt{2}  +\sqrt{5}) \sqrt{3} )\\= \sqrt{3} (\sqrt{3}) (\sqrt{2}  +\sqrt{5}) \)\\= 3 (\sqrt{2}  +\sqrt{5})

In this case it works, sometimes it doesnt, but its always a good start point

➷ Angle XBC = 55 degrees because corresponding angles are equal

b) We already know angle XBC

Angle XCB = Angle XBC because isosceles base angles are equal

Therefore, angle XCB = 55 degrees

Angles in a triangle equal 180 degrees

180 - (55 + 55) = 70

Angle BXC = 70 degrees

➶ Good Luck (:

How do u regroup when u find the sum of 64+43
Anarel [89]
What we are going to do is use the DISTRIBUTIVE PROPERTY. This distributive the numbers, to make it easier to solve.

So we will break 64 up.

64 = 60 + 4

43 = 40 + 3

60 + 40 = 100

4 + 3 = 7

100 + 7 = 107

So, 64 + 43 = 107.

Hope I helped ya!!!!!!!
