Answer:
2 for $3 $3x23=69 then add shipping which equals $74 you can buy 46 pairs.
Step-by-step explanation:
C=2πr and x^2+y^2=r^2
r=4 because of the equation (16)^1/2 is 4
C=8π
Answer:
Step-by-step explanation:
The difference of two squares may be represented by the formula: a^2-b^2,
which can be factored as (a+b)(a-b)
A perfect square trinomial may be represented by the formula: a^(2)-2ab+b^2 or a^(2)+2ab+b^2, depending on the sign of b
if b is negative: use the formula a^(2)-2ab+b^2, which can be factored as (a-b)*(a-b) or (a-b)^(2)
if b is positive: use the formula a^(2)+2ab+b^2, which can be factored as (a+b)*(a+b) or (a+b)^(2)
