Answer:

Perimeter is 17.07

Step-by-step explanation:

We know that DF = EF = 5 cm, since D and E are the midpoints of AC and AB, both of which are 10 cm in length.

We need to use the Pythagorean theorem to get the length of DE.

$DE = \sqrt{5^{2} +5^{2}}=\sqrt{50} = 7.07\\$

So the perimeter of DEF is 5 + 5 + 7.07 = 17.07

yan [13]

Answer:

The answer to your question is: (2a - 1) / 4

Step-by-step explanation:

$\frac{12a^{2} - 3}{2} (2a + 1)^{-2} ( \frac{6}{(2a +1)^{-1} } \\$

$\frac{3(4a^{2} -1)}{2} \frac{1}{(2z + 1)^{2} } (\frac{2a + 1)}{6}$

$\frac{3(2a + 1)(2a- 1) (2a + 1)}{12(2a + 1)(2a + 1)}$

$\frac{(2a - 1)}{4}$

Which expression gives the distance between the points

Anna35 [415]

Answer:

D. √((2 +4)² +(5 -8)²)

Step-by-step explanation:

The distance is found using the formula ...

d = √((x1 -x2)² +(y1 -y2)²)

Selection D has this formula properly filled in with the values ...

(x1, y1) = (2, 5)

(x2, y2) = (-4, 8)
