Answer:
I only used two steps: 3) then 6) then 1).
Step-by-step explanation:
Ok, if x-5 is a factor of p(x), then p(5)=0 by factor theorem.
This also goes the other way around:
If p(5)=0 then x-5 is a factor of p(x) by factor theorem.
Let's check. I'm going to evaluate p(x) for x=5.
This implies x-5 is a factor since we have p(5)=0.
The first step I did was 3) evaluate p(x) for x=5.
The second step I did 6) simplify and find the remainder. I did this when I was evaluating p(5); that was a lot of simplification and then I found the remainder to be 0 after that simplification. The last step was 1) apply the factor theorem, the remainder is 0 so x-5 is a factor of p(x).
2. it has more than two factors
Answer:
Step-by-step explanation:
Arc length of the circle is given by,
Arc length =
Area of the sector of a circle =
22). Arc length of the circle having central angle =
= 60°
Arc length =
=
= 7.33 cm
23). Arc length of the circle having central angle = 225°
Arc length =
= 12.5π
= 39.27 km
24). Central angle =
=
= 225°
Area of the sector =
= 43.20 yd²
25). Area of the sector =
= 65.97 yd²
Answer:
x = 4
Step-by-step explanation:
The absolute value of 5x is still 5x.
5x - 2 = 18
Add 2 to both sides
5x = 20
Divide both sides by 5
x = 4
