The sides of a rectangle are 8cm and 6cm. What is the length of the diagonal. 12cm 10cm 9cm 7cm

tatiyna

Answer:

10 cm

Step-by-step explanation:

The diagonal d divides the rectangle into 2 right triangles with legs 8 and 6 and hypotenuse d

Using Pythagoras' identity in one of the right triangles, then

d² = 8² + 6² = 64 + 36 = 100 ( take square root of both sides )

d = $\sqrt{100}$ = 10 cm

Please help! need answers in order to move on:) will give brainliest if you are correct!

shepuryov [24]

Answer:

1) $x^{2/3}$

$3$ → index

$\sqrt[3]{x^{2} }$

$Index: 3$

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

2) $7^{5/4}$

$=\sqrt[4]{7^{5} }$

$=(\sqrt[4]{7})^{5}$

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

3) $\sqrt[7]{2^{3} }$

$=(2^{3} )^{1/7}$ $[\sqrt[x]{n} =n^{1/n} ]$

$=2^{3/7}$

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

3) $\sqrt[12]{8^{4} }$

$y=(8^{4} )^{1/12}$

$y=(8)^{1/3}$

$y=(2)^{3\times 1/3}$

$y=2$

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

4) $128^{3/7}$

$=\sqrt[7]{2\times 2\times2\times 2\times 2\times2\times 2}$

$=(2)^{3}$

$=8$
