1 answer:

3 0

Make bottom numbers same

convert to improper fraction

1 and 5/6=1+5/6=6/6+5/6=11/6

1/2 and 11/6
2 times 3=6
1/2 times 3/3=3/6

1/2+11/6=3/6+11/6=(4+11)/6=14/6

answer is A

Help me with this pls anyone

podryga [215]

Answer:

Step-by-step explanation:

x^2=3x-2(subtract 3x and add 2) x^2-3x+2=0(group) (x-1)(x-2)=0(find x) x=1;x=2

find y values for x values and check:

1^2=1, pair 1:(1,1); 3(1)-2=3-2=1, same pair

2^2=4, pair 2:(2,4); 3(2)-2=6-2=4, same pair

pairs: (1,1);(2,4)

Which of the following can be a Pythagorean triplets?:

PolarNik [594]

<h2>Answer :-</h2>

As we know that,

Pythagoras triplet

1) a² + b² = c²

Let

$\sf \: {2}^{2} + {2}^{2} = {4}^{2}$

$\sf \: 4 + 4 = 16$

8 ≠ 16

<h3>Hence, A can't be Pythagoras triplet</h3>

2) a² + b² = c²

$\sf \:5 {}^{2} + {12}^{2} = {13}^{2}$

$\sf \: 25 + 144 = 169$

169 = 169

<h3>Therefore, B can be Pythagoras triplet</h3>

3)a² + b² = c²

$\sf {3}^{2} + {5}^{2} = {6}^{2}$

$\sf 9 + 25 = 36$

34 ≠ 36

<h3>Hence, C can't be Pythagoras triplet</h3>

4) a² + b² = c²

$\sf {5}^{2} + {4}^{2} = {7}^{2}$

$\sf \: 25 + 16 = 49$

41 ≠ 49

<h3>Hence, D can't be Pythagoras triplet</h3>

<h2 /><h2>Therefore :-</h2>

Only B can be Pythagoras triplet.
