I think it's 12.
-8 * 3 = -24 and -6÷3=-2
so -24÷-2=12
The two numbers would be 12 and 8 because 12 is 4 more than 8 and so the sum of 12 and 8 is 20.
Becuase 1 is negative and one is postive
Area = 1/2 b * h
h = b - 9
b = b
Area = 56cm^2
Area = 1/2 (b - 9) * b
56 = 1/2 (b^2 -9b)
112 = b^2 - 9b
b^2 - 9b - 112 = 0
b = 16 and therefore the height is
h = 26 - 9 = 7
Check
Area = 1/2 * 16 * 7
Area = 8 *7
Area = 56 which checks.
Answer:
When you are adding or subtracting a negative fraction, you usually want to consider the numerator as negative. The method is just the same, except now you may need to add negative or positive numerators. Example 1: ... To add the fractions with unlike denominators, rename the fractions with a common denominator.
