How to rationalize the denominator of sqrt(a)/sqrt(a)-2

Mathematics
1 answer:
aivan3 [116]3 years ago
3 0

Answer:

√a(√a + 2)          a - 2√a

----------------- = -----------------

    a - 4                a - 4

Step-by-step explanation:

I am assuming that by "sqrt(a)/sqrt(a)-2" you meant:

√a

----------

√a - 2

To rationalize the denom., multiply numerator and denom. of this fraction by the conjugate of √a - 2, which is √a + 2:

√a(√a + 2)

-----------------

    a - 4

Solve for the value of w. * (8w+8)(9w-5)°​
likoan [24]

The solution for the value w is 13 in the equation 8w+8 = 9w-5.

<h3>What is an angle?</h3>

Two rays, referred to as the angle's sides and vertex, come together to form an angle. Angles created by two rays are located in the plane where the rays are located.

Dihedral angles are formed when two planes intersect. The angle formed by the rays lying perpendicular to the two intersecting curves at their point of intersection can also be used to define an angle between two intersecting curves.

Angle is a term used to describe the size of an angle or of a rotation. This metric represents the proportion of a circular arc's length to radius. In the case of a geometric angle, the arc is centred at the vertex and is bound by the sides.

We know that vertical angles of intersection are equal, so here

⇒ (8w+8) = (9w-5)

⇒ 8w+8 = 9w-5

⇒ 9w - 8w = 8 + 5

⇒ w = 13

Angle measure = 8(13)+8

                          = 112°

A 13-foot ladder leans against the side of a house with its base 3 feet from the house. Use the Pythagorean Theorem to approxima
wlad13 [49]

Answer:

12.65

Step-by-step explanation:

The formula for Pythagorean Theorem is 'a' squared + 'b' squared = 'c' squared. So let's call the base of this triangle, which is 3, 'a' and the length, which is the hypotenuses, 'c'. Now we need to plug it in. So, we square 3 and square 13. It's now (9+b=169). Solve the equation and you get b^2=160. So now we solve for the square root. And the answer is 12.6491106407 which you can round to 12.65

in each variety pack of fruit juice, there are 3 voxes of apple juice, 2 boxes of grape juice, and 1 box of orange juice. In a d
Rasek [7]
384 boxes of juice are in the display because if they are 3 in each pack and each case has 8 then just do 8 * 3 which is 24. But since there are 16 cases you would take 24 and times that by 16 which would equal 384, the total number of juice boxes. I hope this helps!

Please answer correctly, will mark brainliest, thanks! ^-^
kotykmax [81]

Answer:

The first Answer is five because four times five plus ten is 30 and fives times six is 30

The second answer is X equals 3 because if you plug in 11x for y then add that to the existing x you get 12 and if you divide 36 by 12 you get 3
