Answer:

x = 1/2 or .5

Step-by-step explanation:

JK = 7x + 2, KL = 5x + 4 and JL = 12

JK + KL = JL

Plug in the equations for the Lines

7x + 2 + 5x + 4 = 12

Combine like-terms

12x + 2 + 4 = 12

12x + 6 = 12

Subtract 6 from either side

12x + 6 = 12

-6 -6

12x = 6

Divide either side by 12

12x / 12 = 6/ 12

x= 1/2 or .5

Which of the following could be the side lengths of a right triangle?

choli [55]

Recall that in a right-triangle, the hypotenuse, or longest side, is √(a²+b²).

$\bf \sqrt{4.1^2+6.2^2}\qquad \approx\qquad 7.43303437
\\\\\\
\sqrt{40^2+60^2}\qquad \approx\qquad 72.1110255
\\\\\\
\sqrt{3.2^2+5.4^2}\qquad \approx\qquad 6.27694193
\\\\\\
\sqrt{33^2+56^2}\qquad =\qquad 65$
