215 is the answer because 78-35 =43 43×5=215
They each have $42 because 7 times 6 is 42 and combined they have $84 because 42 + 42=84.
Answer:
Option A
Step-by-step explanation:
We can try to factorize all the options one by one.
For A:

We can see that the quadratic expression cannot be solved by factorization as the factors at the end of factorization are not equal in both brackets. So Option A is the correct answer for the given question.
Moreover we can also note that all the other quadratic expressions can be factorized ..
5x-5=0
You simplify the left side
