Answer:
x = 3
Step-by-step explanation:
6x + 2x - 5= 19
8X -5 = 19
8x = 24
x = 3
The pattern is dividing by 2 every time so the next 3 numbers will be 1/8, 1/16, 1/32

Answer:
x = 17
Step-by-step explanation:
This is a right triangle so we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
15^2 + x^2 = (sqrt(514))^2
225 + x^2 = 514
Subtract 225 from each side
225-225 + x^2 = 514-225
x^2 =289
Take the square root of each side
sqrt(x^2) = sqrt(289)
x = 17
A) (f + g)(x) = f(x) + g(x) = (5x-12) + (11x+2) = 16x-10
B) (f × g)(x) = f(x)×g(x) = (5x-12)×(11x+2) = 5x(11x) -12(11x)+2(5x) -12(2) = 55x² -122x -24
C) f(g(x)) = 5(11x+2) -12 . . . . substitute g(x) for the x in f(x)
... = 55x +10 -12 = 55x -2
