Step-by-step explanation:
Answer:
No
Step-by-step explanation:
you can check with the pythagorean theory
64 + 81 = 144
145 = 144
this is not true, therefore those side lengths do not make a right triangle.
I believe the correct answer from the choices listed above is the first option. The equation that can be used to solve the problem would be x + (x + 9) = 47.
<span>The sum of two numbers is 47. ---> x + y = 47 where x is the smaller number and y is the larger.
</span><span>The greater number is 9 more than the smaller number. -----> y = x + 9
x + ( x + 9 ) = 47</span>
<span>Assuming that 2 people who will repair a refrigerator equally fast will do it twice as fast when working together:
Jannete repairs 1/60 refrigerator per minute.
Lisa repairs 1/40 refrigerator per minute.
Togheter they repair 1/60+1/40= 1/60 + 1,5/60 = 2,5/60=5/120=1/24 refrigerator per minute
thus it will take them 24 minutes</span>
