Solve 2x2 + 20x = −38.
cestrela7 [59]
2x^2+20x=-38  divide both sides by 2

x^2+10x=-19, halve the linear coefficient, square it, than add that value to both sides of the equation, in this case add (10/2)^2=25...

x^2+10x+25=6  now the left side is a perfect square

(x+5)^2=6  take the square root of both sides

x+5=±√6  subtract 5 from both sides

x=-5±√6    (so answer c.)

What is the total surface area of a right circular cylinder with base radius 7cm and height 12cm.
mojhsa [17]

Answer:

Using 3.14  for pi

835.24 cm^2

Using the pi button for pi

835.6636459 cm^2

Step-by-step explanation:

The surface area of a cylinder is given by

SA = 2 pi r^2 + 2 pi r h

     = 2 * pi ( 7)^2 + 2 pi ( 7) * 12

    = 98 pi + 168 pi

    =266 pi
