Step-by-step explanation:
x³ - 4x² + x - 4
= x²(x - 4) + (x - 4)
= (x² + 1)(x - 4).
Since the quadratic factor (x² + 1) is irreducible any further, this is our answer.
Ok so its a guessing game
I say its 40+10 because
40-10{one # is 10 less than)=30
10(3){three times the other number}=30
so 40+10=50
19 - 4.07
14.93
hope this helps
The angles of all triangles should always sum up to be 180, so knowing this we can solve this problem using the equation x + 3x + 5x - 54 = 180, first we want to combine all our common variables, so we add the x’s together and get 9x - 54 = 180 then we add +54 to both sides so that the x can be by itself and we have 9x = 234, we divide both sides by 9 and get our final answer of x = 26
