9x10 to the -8th power.
Since the numbers are both x10^-8, you can simply add 2 and 7. If you would rather look at it as:
0.00000007 + 0.00000002 = 0.00000009 = 10x10^-8
then you will get the same answer.

Answer: Letter Choice ( B): -x^2 - 4x + 7
Step-by-step explanation:
( 4x^2 - 7x + 9 ) - ( 5x^2 - 3x + 2 )
Remove Parentheses: (a) = a
4x^2 - 7x + 9 - ( 5x^2 - 3x + 2 )
- ( 5x^2 - 3x + 2 ): - 5x^2 + 3x - 2
Simplify:
4x^2 - 7x + 9 - 5x^2 + 3x - 2
