The square root -38 is sqrt(38)i, or approximately 6.2i.
Answer:
b
Step-by-step explanation:
We have to use the functions:
h ( x ) = 2 x + 5 and t ( x ) = 7 x - 6
Part A:
( h + t ) ( x ) = ( 2 x + 5 ) + ( 7 x - 6 ) = 9 x - 1
Part B :
( h · t ) ( x ) = ( 2 x + 5 ) · ( 7 x - 6 ) = 14 x² - 12 x + 35 x - 30 =
= 14 x² + 23 x - 30
Part C :
h [ t ( x ) ] = h ( 7 x - 6 ) = 2 · ( 7 x - 6 ) + 5 = 14 x - 12 + 5 =
= 14 x - 7
Hello!
First, let's write the problem.

Subtract 3x from both sides.


The opposite of division is multiplication, so we are going to multiply in order to undo the fraction.

Our final answer would be,
