Completing the square goes back to pythagorean thm
but the way u do it, u want to find a value that enable u to take sqrt of both sides and solve
x^2-8x+3=0
x^2-8x=-3
we need (x-4)^2 so add 16
(x-4)^2=-3+16
(x-4)^2=13
x-4=sqrt13
x=4(+/-)sqrt13
Average price=total price/total weight, let p be the average price:
p=(3*4+5*4*(100-20)/100)/8
p=(12+16)/8
p=$3.50/lb
Given:

Required:
Length of an arc x.
Explanation:
Length of an arc is given as,

Length of an arc is calculated as,

Answer:
Thus the value of the length of an arc is 15.5091 mm
Answer:
13.89
Step-by-step explanation:
12² + 7² = C
144 + 49 = 193
√193 = 13.89
round it if u want
Answer:
B)
Step-by-step explanation:
A, C, and D multiple choice answers have no chance of becoming a triangle because the lengths don't add up to either 180 or 90. Also, Triangle B follows the rule that 2 sides and be greater than the other side.
