Answer:
(x+1)(x²-4x+1)
Step-by-step explanation:
f(x) = x³-3x²-3x+1
= (x³+1) - 3x (x+1)
= (x+1)(x²-x+1) - 3x(x+1)
= (x+1)(x²-x+1-3x)
= <u>(x+1)(x²-4x+1)</u>
<u />
** (x+1)(x²-4x+1) = (x+1)((x-2)² - 3)
= (x+1)((x-2)² - (√3)²)
= (x+1)(x-2-√3)(x-2+√3)
This is simple algebra :)
First, we can write the question as an algebraic equation.
Given that Doug spent 40 more hours than Laura, we can represent Laura as (x) and Doug as (x+40).
"Doug and Laura spent a combined 250 hours." So we can write this as
(x) + (x+40) = 250
Now simplify:
2x + 40 = 250
Solve x by subtracting 40 from both sides of the equation:
2x = 210
Therefore:
x = 210/2
= 105
So Laura (x) spent 105 hours!
Answer:
70
Step-by-step explanation:
we have the angle of vertex in the isosceles triangle = 180-2*bottom coner= 180-65/2=50
3 angles in the equilateral triangle are equal to 60
we have 50 + 60 +h =the angle of PQR =180
h=70
