Step-by-step explanation:
x³ - 4x² - 25x + 100k
= x²(x - 4) - 25(x - 4k)
= (x² - 25)(x - 4k)
= (x + 5)(x - 5)(x - 4k)
Hence the other 2 zeroes are x = -5 or x = 5.
X = 9
Add both values 7 + 2 = 9, which is x.
9 - 2 = 7.
It’s between B or C
Sorry if I’m wrong
To let the variable alone you can follow these steps: 1) subtract 228 from both sides 2) divide both sides by 4. This is the solution: 1) 4y + 228 - 228 = 352 - 228 => 2) 4y = 124 => 3) (4y)/4 = 124/4 => 4) y = 31. Then, <span>the answer is the option A. y = 31. </span>
