Apply the Pythagorean Theorem to find the distance between points B and C. A) 18 units B) 55 units C) 64 units D) 73 units

Answer:

$BC=\sqrt{73}$

Step-by-step explanation:

Notice that A, B, and C constitute the vertices of a right angle triangle, with the right angle at the vertex A.

If we count the number of squares separating B and A (one of the legs of the right angle triangle) we find 8 units.

If we count the number of squares separating C from A (the other leg of the right angle triangle), we get: 3 units.

Then, we apply the Pythagorean theorem to find that length of the triangle's hypotenuse which is the segment BC:

$BC=hyp=\sqrt{8^2+3^2} =\sqrt{64+9} =\sqrt{73}$

qaws [65]

I'd say what you would do is: You can either 1. Add 15 and 18 together and then divide by 2 OR 2. Since there is a 3 number difference between 15 an 18, just add 3 to 18

Can some one solve this (squar roots)

Inessa05 [86]

Answer:

2 $\sqrt{6}$

Step-by-step explanation:

Using the rule of radicals

$\sqrt{a}$ × $\sqrt{b}$ ⇔ $\sqrt{ab}$

Simplifying the radicals

$\sqrt{96}$

= $\sqrt{16(6)}$

= $\sqrt{16}$ × $\sqrt{6}$ = 4 $\sqrt{6}$

$\sqrt{24}$

= $\sqrt{4(6)}$

= $\sqrt{4}$ × $\sqrt{6}$ = 2 $\sqrt{6}$

Thus

$\sqrt{96}$ + 2 $\sqrt{6}$ - 2 $\sqrt{24}$

= 4 $\sqrt{6}$ + 2 $\sqrt{6}$ - 4 $\sqrt{6}$ ← collect like terms

= 2 $\sqrt{6}$
