Answer:
(c) x² -64
Step-by-step explanation:
The factoring of the difference of squares is one of the special forms we use in the study of polynomials. It tells you ...
a² -b² = (a +b)(a -b)
__
You have a factor (x +8), so a=x, b=8, and the "expanded" form is ...
a² -b² = x² -8² = x² -64
Answer is 9(-2)=-18 but that choice doesn't appear in your list of answers
Answer:
Number of white marbles in the bag = 45
Step-by-step explanation:
Total number of marbles in the bag = 135
Ratio of white marble to transparent ones = 3 : 6

Total number of marbles will be 
So we have.

Dividing both sides by 9.

∴ 
∴ Number of white marbles in the bag =
