Answer:
D) 3
Step-by-step explanation:
-3x+6=2x-9
<em>subtract 6 from both sides</em>
-3x=2x-15<em> </em>
<em>subtract -2x from both sides</em>

<em>divide both sides by -5</em>
x= 3
Answer:
( x + 7 ) ( x + 3 )
Solutions are -7 , -3
Step-by-step explanation:
x² + 10 x + 21
x ( x + 3 ) + 7 ( x + 3 ) = 0
( x + 7 ) ( x + 3 )
Factors = 3 , 7
Sum = 21
Product = 10
The sine of 1/2 the angle = 13 / 32
so this angle = 23.9695 degrees
Therefore the required angle = 2 * 23.9695 = 47.939 to 3 DP's.
