Answer:
Step-by-step explanation:
Answer:
no, it cannot
Step-by-step explanation:
a difference of square is: a² - b² = (a - b)(a + b)
looking at the expression (5z+3)(-5z-3), we see that it does not fit the criteria of the breakdown of a perfect square, as (-5z-3) has a negative <em>a</em> term (-5z)
if we FOILed (5z+3)(-5z-3) out, we would get:
-25z² - 30z - 9, which is not a difference of squares
Question #1's answer is 6,000,000 + 7,000 + 2000
Question #2's answer is 30,000,000 + 2,000,000 + 5,000 + 8
Hope that helps :)
