Given f(x) = 3x + 5 and g(x) = -8x - 10 a. find f(x) + g(x) b. find f(x) - g(x) c. find f(x) x g(x) d. find f(x)/g(x) e. determine which of the above are polynomials.

a: f(x) + g(x) = 3x+5 -8x-10 = -5x-5 = -5(x+1)

b: f(x) - g(x) = 3x+5 +8x+10 = 11x + 15

c: f(x) x g(x) = (3x+5) (-8x-10)= -24x^(2) - 30x - 40x - 50 = -24x^(2) - 70x - 50

d. f(x)/g(x) = -3/8   +  5/(4(-8x-10)

(3x+5)/(-8x-10):  

numerator: 3x+5

denominator:(-8x-10)

quotient: -3/8

remainder:5/4

e. Determine which of the above are polynomials.

f(x)/g(x)

distance covered by pamela in 9 l of fuel = 99km

let us apply unitary method here.

distance covered by pamela in 1 l of fuel =99/9 =11 km

now let us find distance covered by pamela if she has 12 l of fuel.

distance covered in 12 l = distance covered in 1 l of fuel * 12

we know that distance covered by here in 1 l is 11 km.

so distance covered in 12 l of fuel = 11*12 = 132 km.

yes
