There is only one solution in the given equation -y2 − [-5y − y(-7y − 9)] − [-y (15y + 4)] = 0. In solving this problem, apply first PEMDAS (parenthesis, exponents,multiplication, division, addition, subtraction). Then equation will transform into -y2+5y-7y2-9y+15y2+4y=0. Combine terms with same power and achieve 7y2=0. Divide both sides with 7 and perform square root of zero. Since the root is zero, we have one solution of the given equation which is y=0.
Answer:
Area = 87.9646 sq. units from A = 28*π sq. units.
However I cannot see this in your answer list, since the numbers look all jumbled. Choice A. looks close to it, since there is a 28...
Step-by-step explanation:
We have a cylinder with height h = 5
radius = 2
We want the surface area of this cylinder.
A = (circumference)*h + 2*(pi)*r^2
A = ( 4*π)*5 + 2*π*(2^2)
A = 20π + 8π = 28 π square units
A = 87.9646 sq.. units
