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
Answer:
Step-by-step explanation:
if 26 books were sold in 2.5 hours
26 books.......................................2.5 hours
? books............................................10 hours
the books sold in 10 h
=(26*10)/2.5=104
Answer:a
Step-by-step explanation:
⇒ d + e + f = b + a + a + c + b + c
⇒ d +e + f = 2a + 2b + 2c
= 2(a + b + c)
But, according to triangle angle sum theorem,
a + b + c = 180 degrees
Therefore, ⇒ d +e + f = 2(180°)
= 360°
