There are two ways to solve this question.
1) To solve this question, we need to substitute a = 6 and b = -3 into the given expression and then evaluate:
(-a)(b)(-a + b)
= (-6)(-3)(-6 + (-3))
= 18(-9)
= -162
2) An alternative method is to simplify (-a)(b)(-a + b) into an expression without brackets and then substitute a = 6 and b = -3:
1. (-a)(b)(-a + b)
= (-ab)(-a + b)
= -ab*(-a) + (-ab)*b
= a^(2)b+ (-ab^(2))
= a^(2)b - ab^(2)
2. a^(2)b - ab^(2)
= 6^(2)*(-3) - 6*(-3)^2
= 36*(-3) - 6*9
= -108 - 54
= -162
The key to either method is to be careful with placement of brackets, especially where there are negative values involved.
The answer is q=55
if you put in 55 it works
Answer:
incorrect, not, 6.37
Step-by-step explanation:
I don't know the drop down options but hope this helps. Basically, Marco is wrong (incorrect) because 63.70 is not 63.7. The zero in 63.70 is not needed. Its just there (I forgot why oops). So if you divide 10 from 63.7 then you got 6.37.
Perhaps it is July, I think it is the hotest month of summer.
