Answer:
6+(-2)
Step-by-step explanation:
6 is positive but we are subtracting 2. Therefore, the expression is 6 plus -2. It is negative because that is what we are taking away. The plus sign does not mean anything because there is a negative number. When you look at it, you immediately read 6 plus -2 and since it is a negative not a positive then it's subtracting not adding.
Answer:
2x² +2x - 12
Step-by-step explanation:
area of rectangle = length X width
length = x+3
width = 2x - 4
Area = (x+3)(2x-4)
= x(2x-4) +3(2x-4)
= 2x² - 4x + 6x - 12
= 2x² +2x - 12
