I need help answering this question
My name is Ann [436]

Answer:

55

Step-by-step explanation:

JL = JK + KL

84 = 3x+5  + 6x+7

Combine like terms

84 = 9x +12

Subtract 12 from each side

84-12 = 9x+12-12

72 = 9x

Divide by 9

72/9 = 9x/9

8 =x

We want KL

KL = 6x+7

   6*8 +7

    48+7

     55

Solve (9^62773 + 2)^83721
shutvik [7]
Remember the order of operations and do what is in parenthses first. 

Take 9 to its power first, then add 2. Once you get that, take that answer to the 83721 power. 

I would give you the answer, but my calculator is saying invalid input every time I am trying to use such high exponents. Sorry :( But I hope that this helps
