-1 + 6x = - 2 |add 1 to both sides
6x = -1 |divide both sides by 6
x = - 1/6
Answer:
B
Step-by-step explanation:
49x^2=9
solve for x
x^2= 9/49
x=±
which is x = ±3/7 (B)

Answer:
Surface area of cylinder= 211.5π
Step-by-step explanation:
Given,
Height of cylinder = 19cm
Diameter of cylinder = 9cm
i.e Radius of cylinder = diameter/2 = 9/2 = 4.5cm
Surface area of cylinder = 2πrh + 2πr²
Plug corresponding values of r and h in surface are formula.
Surface area of cylinder = 2πrh + 2πr² = 2π*4.5*19 + 2π*4.5²
Surface area of cylinder = 171π+40.5π = 211.5π
Hence we get surface area of cylinder= 211.5π
