F(x) = 5x and g(x) = x + 11.

which of the following represents h(x) = f(x)g(x)?

h(x) = 5x + 55
h(x) = 5x + 55x
h(x) = 5x2 + 55x < correct answer
h(x) = 5x2 + 55

C

Step-by-step explanation:

f(x) × g(x)

= 5x(x + 11) = 5x² + 55x, thus

h(x) = 5x² + 55x → C

the answer will be

x =±sqrt(1/3)

step-by-step explanation:

x+4/6x=1/x

multiply each side by 6x to get rid of the fractions

6x*(x+4/6x)=1/x*6x

distribute

6x^2 +4 = 6

subtract 4 from each side

6x^2 +4-4 = 6-4

6x^2 =2

divide by 6

6x^2/6 = 2/6

x^2 = 1/3

take the square root of each side

sqrt(x^2) = ±sqrt(1/3)

x =±sqrt(1/3)
