Solve the following exponential question:

x = - 0.55 ( 2 dec. places )

Step-by-step explanation:

Express as

. 4² - = 7

Factor out from each term

( 4² - 1) = 7

× 15 = 7 ( divide both sides by 15)

=

Take the log ( base 10 ) of both sides

log = log (), thus

x log 4 = log ( ) ( divide both sides by log 4 )

x = - 0.55

i need the table so i can see

step-by-step explanation:

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
