Let $x$ be the positive number such that $2x^2 = 4x + 9.$ If $x$ can be written in simplified form as $\dfrac{a + \sqrt{b}}{c}$ such that $a,$ $b,$ and $c$ are positive integers, what is $a + b + c$?

sorry can't

step-by-step explanation:

i googled though and something came up but it was in science langueage not common english sooo

is there supposed to be a diagram or a graph for this one? ?

step-by-step explanation:

inverse property is the answer

step-by-step explanation:

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base

option a
