Answer:
a no solution
b is all real numbers
c x=12
Step-by-step explanation:
a has no values of x that make it true
b any value of x makes it true
c simplify both sides of the equation then isolate x
Answer: 300
Step-by-step explanation:
208.81 square centimeters of aluminium are needed
<em><u>Solution:</u></em>
Given that,
Radius = 3.5 cm
Height = 6 cm
We have to find the square centimeters of aluminum needed
So we have to find the surface area of cylinder
<em><u>The surface area of cylinder is given by formula:</u></em>

Where "r" is the radius and "h" is the height of cylinder
<em><u>Substituting the values we get,</u></em>

Thus 208.81 square centimeters of aluminium are needed
F(-1) = 12 - 5(-1)
f(-1) = 12 + 5
Solution: f(-1) = 17
