3\sqrt{7} is the answer obtained when the perfect squares  are removed from \sqrt{63}

<u>Step-by-step explanation:</u>

  • \sqrt{63} is written as the \sqrt{9*7}.
  • Thus the 9 is the perfect square of 3 so by taking 9 out of the square root it becomes 3
  • Thus the answer is 3 \sqrt{7}
  • Perfect square is said to be the number which is obtained by the twice the product of the every number.

Show that the sum of the reciprocals of three different positive integers is greater than 6 times the reciprocal of their produc
Montano1993 [528]
If a,b,c are the 3 positive integers
1/a +1/b +1/c > 6/abc
(bc+ac+ab)/abc >6/abc so
(bc+ac+ab)>6
The lowest positive integers that are different are 1,2,3 so the lowest value that (bc+ac+ab) could have is 1•2+2•3+1•3=2+6+3= 11 therefore
1/a +1/b +1/c > 6/abc is true

S=(l)(b)(b) solve for s
Alona [7]
I’m not entirely sure but i think it might be s=lb^2 because the l, b, and b are all being multiplied together, and since you are multiplying and not adding the b’s, the two would go to b^2, and then you just multiply by l to get lb^2

What is an equation of the line that passes through the points (-3, 7) and (3, 3)?
Margarita [4]

Answer:

y = -\frac{2}{3}x + 5

Step-by-step explanation:

First you have to find the slope

m = \frac{7 - 3}{-3 - 3} = \frac{4}{-6} = -\frac{2}{3}

Now use the point-slope form by using one of the points and the slope.  Let's use the point (3, 3)

y - 3 = -\frac{2}{3} (x - 3)

Multiply thru the equation by 3 to remove the fraction

3y - 9 = -2(x - 3) =

3y - 9 = -2x +6

3y = -2x + 15

y = -\frac{2}{3}x + 5 is the equation in slope-intercept form
