Answer:

Step-by-step explanation:

Just like in the last problem, we have a right triangle but in this case, x is a leg, 10 / 2 = 5 is the other leg, and 13 is the hypotenuse. Using the 5 - 12 - 13 Pythagorean Triple, we know that x = 12.

Use three different values of n to demonstrate that 2n + 3n is equivalent to 5n.

Rainbow [258]

You could use 10, 6 and 7.

Using ten would have them all equal 50, using 6 would have them all equal 30 and using 7 would have them all equal 35.

Hope this helps!

What is the value of x after these statements if the starting value of x is 3.

kolbaska11 [484]

[A]
$3^{2}=9$
$5^{3}=125$
$9\neq25$

Ignore

[B]
$3^{2} = 9$
$9 \ \textgreater \ 3$
Yes

$3^{3}=27$
$4( 3^{2})=36

27 \ \textless \ 36$
Yes

Therefore
$x=3+2=5$

[C]
$4^{5}=1024

 5^{4}=625

1024\ \textless \ 625$
No

$5^{5}=3125

 5^{5}=3125

3125\ \textgreater \ 3125$
No

Ignore

[D]
$5^{5}=3125

 2^{5}=32

3125\ \textgreater \ 32$
Yes

$5^{2}=25
25\ \textless \ 11$
No

Therefore
$x=5+8=13$

[E]
$8\ \textgreater \ 7$
Yes

Therefore
$x = 13^{2}=169$
