Which of the following is not a Pythagorean triple?

Vinil7 [7]

Answer: D,(11,61,62)

Step-by-step explanation:28,45,53

53²=28²+45²

2,809= 784+2,025

= 2,809

53²=2,809

(28,45,53) is a Pythagorean triple

16,63,65

65²=16²+63²

4225=256+3969

= 4225

65²=4225

(16,63,65) is a Pythagorean triple

13,84,85

85²=13²+84²

7225=169+7056

=7225

85²=7225

(13,84,85) is a Pythagorean triple

11,61,62

62²=11²+61²

3,844=121+3,721

=3,842

62²=3,844

(11,61,62) is not a Pythagorean triple

7(5x + 9) = 12 - (x +9)

den301095 [7]

Answer:

$\frac{-5}{3}$ is the answer

Step-by-step explanation:

7(5x+9)=12+−1(x+9)(Distribute the Negative Sign)

7(5x+9)=12+−x+−9

(7)(5x)+(7)(9)=12+−x+−9(Distribute)

35x+63=12+−x+−9

35x+63=(−x)+(12+−9)(Combine Like Terms)

35x+63=−x+3

Add x to both sides.

35x+63+x=−x+3+x

36x+63=3

subtract 63 from both sides.

36x+63−63=3−63

36x=−60

Divide both sides by 36.

$\frac{36x}{36} =\frac{-60}{36}\\$

-5/3 is the answer.

ik this doesnt make any sense but hope this helps
