HELP ASAP BEING TIMED! If Triangle J K L is congruent to Triangle B C A, which statement must be true?
Vlada [557]

Answer:

Choice C

Step-by-step explanation:

This is like a matching question. Here's what I mean by this. We know Triangle BCA and Triange JKL are congruent. So, what we have to do is match the side lengths together.

So the first side of BCA matches with JKL, the second side of BCA matches with JKL, the third side of BCA matches with JKL.

So first side:

BC is congruent  to JK

So second side:

CA is congruent  to KL

So third side:

JL is congruent  to BA

The third side is one of our answer choices.

That answer choice is C.

Please Hurry! What is the solution to log2_(9x)-log2_3=3?
brilliants [131]

Answer:

log_{2}(9x)  - log_{2}(3) = 3 \\ 3 =  log_{2}(8) or log_{2}( {2}^{3} )  \\  log_{2}( \frac{9x}{3} )  = log_{2}(8) \\  \frac{9x}{3}  = 8 \\ 9x = 8 \times 3 \\ 9x = 24 \\ x =  \frac{24}{9}  \\ x =  \frac{8}{3}  \\ x = 2 \times \frac{2}{3}
