x= 3+√5/4,3-√5/4
Step-by-step explanation:
1.In general, given ax^2+bx+c=0, there exists two solutions where:
x= -b+√b^2 - 4ac/2a, -b-√b^2-4ac/2a
2.In this case, a=4, b=-6 and c=1.
x=6+√(-6)^2-4×4/2×4, 6-√(-6)^2-4×4/2×4
3.Simplify.
x=6+2√5/8, 6-√5/8
4.Simplify solutions.
x=3+√5/4, 3-√5/4
Answer:
The area of the regular pentagon is 
Step-by-step explanation:
we know that
The area of a regular polygon is equal to

where
P is the perimeter of the regular polygon
a is the apothem
Find the perimeter P
----> the regular pentagon has five equal sides
---> distance from center to middle of side
substitute


Answer:
Store Z
Step-by-step explanation:
Store X: 4 cans for $2.48, so 2.48/4= $0.62 per can
