Answer:
Area = 14.8
Step-by-step explanation:
Area = 5/2 + a^2*sqrt(5 + 2 sqrt(5) )
This formula given the side length, calculates the area.
a = 2
Area = 2.5 + 2^2 * sqrt(5 + 2*sqrt(5) )
Area = 2.5 + 4 * sqrt(5 + 2*2.236)
Area = 2.5 + 4* sqrt(5+ 4.4721)
Area = 2.5 + 4*sqrt(9.4721)
Area = 2.5 + 4*3.0776
Area = 2.5 + 12.3107
Area = 14.8107
No that is correct. it is 90 people. because 60% of 150 people is 90 people not 80
Answer:
Positive.
Step-by-step explanation:
(self-explanatory)
5+3x=23 x=6 the answer is 6
Distribution method
(2x+6)(2x-6)
=4x^2-12x+12x-36
=4x^2-36
