ANSWER

2 \sqrt{42} +7  \sqrt{2}- 6- \sqrt{21}

EXPLANATION

The given product is:

( \sqrt{14}  -  \sqrt{3} )( \sqrt{12} +  \sqrt{7}  )

We expand using the distributive property to obtain:

\sqrt{14}( \sqrt{12} +  \sqrt{7}) -\sqrt{3}( \sqrt{12} +  \sqrt{7}  )

Extract the perfect squares to get:

\sqrt{14}(2 \sqrt{3} +  \sqrt{7}) -\sqrt{3}( 2\sqrt{3} +  \sqrt{7}  )

Expand further to get;

2 \sqrt{42} +7  \sqrt{2}- 2(3)   - \sqrt{21}

This simplifies to,

2 \sqrt{42} +7  \sqrt{2}- 6- \sqrt{21}

In the diagram, m∠COE = 55°. If m∠2 = 2x and m∠3 = x + 10, what is the measure of angle 2?
Mila [183]
<span>Subtract 55 from 180 total degrees of a triangle to get 125. Put 2x and x + 10 together... 3x + 10 = 125 Subtract 10 from both sides... 3x = 115 Divide by 3... x = 38.3333 Now to find the measure of angle 2... 38.333(2) = 76.66666 Don't know if that's a multiple choice question or not, but that's what I got</span>

Please help. The correct and best answer gets brainiest! 29 points!!
attashe74 [19]

Answer:(15, 100)

Step-by-step explanation:

first find the coordinates of the point above (3, 20)

you just look at the x axis and where the point is in this case x would be 6 and then you find y which would be 40

so the coordinate would be (6, 40)

now subtract (6, 40) by (3, 20)

6-3= 3

40- 20= 20

you get the first coordnites which is what you add (12,80) to

12 +3= 15

80+ 20= 100

you get the coordinates (15, 100)

−3 2/7−(−5/7) plz help me
balu736 [363]

Answer:

-2 or -14/7 (they're the same)

Step-by-step explanation:

  1. Write it out: -3\frac{2}{7} - (-\frac{5}{7})  
  2. Simplify. It should now look like this: -3\frac{2}{7} + \frac{5}{7}  
  3. Turn -3 2/7 into an improper fraction. It should now look like this: -19/7
  4. Add: -\frac{19}{7} + \frac{5}{7} = -\frac{14}{7} = -2  

I hope this helps!
