You can't solve this unless you have numbers to substitute or another equation.
I think the answer is a=2
Answer:
b. {-9, 3}.
Step-by-step explanation:
x^2 + 6x - 27 = 0
We need 2 numbers whose product is -27 and whose sum is + 6.
These are + 9 and - 3. So the factors are:
(x - 3)(x + 9) = 0
(x - 3) = 0 or (x + 9) = 0
x = 3 or -9.
Its 252,889 because when your taking 428,731 from 175,842 your subtracting the bigger number from the little number & if you take 252,889 and add it too 175,842 you get 428,731.
Well then multiply 400 x 142 and get your answer of 56,800
