Answer: 4x^2−4x+1
Step-by-step explanation:
(2x-1)^2
Square of Difference: (a−b)^2=a^2−2ab+b^2.
(2x)^2−2*2x+1
Multiplication Distributive Property: (xy)^a=
2^2x^2−2*2x+1
4x^2−2*2x+1
4x^2−4x+1
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

Answer:
216°
Step-by-step explanation:
The ratio of the sum of smallest and largest to the total of all angles is ...
(9 +15)/(9 +10 +12 +14 +15) = 24/60 = 0.4
__
The total of all angles in an n-gon is 180°(n -2), so the total of all angles in a pentagon is ...
180°(5 -2) = 540°
Then the sum of smallest and largest angles is ...
0.4(540°) = 216°
In order to have the variable by itself you have to add 20 to both sides. So your answer would be a=b+20. I hope this helps love! :)

Answer:
- vertical change: 1 unit
- horizontal change: 2 units
- rate of change: 0.5
Step-by-step explanation:
The marks on the graph show the vertical change is 1 unit, and the horizontal change is 2 units.
The "rate of change" is the ratio of vertical change to horizontal change:
rate of change = slope = Δy/Δx = 1/2 = 0.5
Expressed as a decimal, the rate of change is 0.5.
Answer:
362880
Step-by-step explanation:
You have to subtract the two people who are already doing something in line so you would do 11-2 which equals 9. Then you would do 9 mPr 9 which gives you an answer of 362,880.
