283.5 because 6.75 times 21 is 141.75 then u need to mulitply it by 2.
Answer:
4a-4b
Step-by-step explanation:
In the numerator, we can simplify this: (2a-2b)^2 = ((2)(a-b))^2 = (2)^2(a-b)^2 = 4(a-b)^2 = 4 (a-b)(a-b). Thus, we get: (4(a-b)(a-b))/(a-b). We can cancel the top and bottom with a-b and get: 4(a-b) = 4a-4b.
I hope this helps!
Equal to 3n+p
