Answer:
3 to the 3rd power is the answer because 3x3x3=27
The last one , because I will now solve it for you and prove therefore.
x²–4x+5=0;
D=(–4)²–4•5=16–20= –4= (2i)².
So:
x1= (4–2i)/2= 2–i
x2= (4+2i)2= 2+i.
This is the whole answer....
Three other u will solve by yourself and have roots which will not be suitable.
Answer: 200 feet longer
Step-by-step explanation:
8,556 rounded to the nearest hundred is 8,600
8,371 rounded to the nearest hundred is 8,400
8,600-8,400=200
Area=legnth times width
we notice this is a special case
(a+b)(a-b)=a^2-b^2
area=(a+3b)(a-3b)=a^2-9b^2
area=a^2-9b^2
