Answer:
160+3x=195-2x
Step-by-step explanation:
So if Nick is 160 lbs and Adam 195, and Nick is gaining 3 pounds per week and Adam is losing 2 pounds per week then you have to use a variable to find the unknown which is the number of weeks. So a gain is positive or addition and a loss is negative of subtraction. Then to solve it put the variables together and the numbers together. The opposite of -2x is 2x so 3x plus 2x and 195 plus the opposite of 160 which is -160 then solve for x.
(a² + b² - 2ab) + 2ac - 2bc = (a - b)² + 2c(a-b) = (a-b)(a-b +2c)
It is not equivalent because 3 (5x)= 15x while (3×5) (3×x)=15+3x they turn out different when you do the distributive property
The answer is either c or b because i think they are the same
