For a long time, mathematicians weren't sure that asymmetric encryption was possible. Fortunately, cryptographers discovered the necessary mathematical innovation in the 1970s and invented public key encryption. If public key encryption was never invented, what wouldn't be possible today?

here is a big fat

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2

good luck on ur quiz test or homework. have a good day : )
