2.5=2x
2.5/2=x (of course when dividing by a fraction you multiply by the reciprocal so it would be 5/2*2/1
x=5/4
Answer:
43.75
Step-by-step explanation:
(8*3.5)/2 + (8*3/5)/2 + (4.5*3.5)/2 + (4.5*3.5)/2 =
8*3.5 + 4.5*3.5 = 28 + 15.75 = 43.75
The picture helped a lot
Given f(x) = x^2 - 7x + 12 and g(x) = 3 / (x^2 - 16)
The product of the two functions, <span>(f•g)(x) is equal to:
(x^2 - 7x + 12) * 3 / (x^2 - 16)
To simplify, factor the two polynomials:
x^2 - 7x + 12 = (x - 4 ) (x - 3 )
x^2 - 16 = (x - 4) (x +4)
=> </span><span>(f•g)(x) = (x - 4)(x - 3) * 3 / [ (x - 4) (x +4) ] = 3 (x - 3) / (x + 4)
Answer: 3 (x - 3) / (x + 4)

Answer:
Step-by-step explanation:
g(x^2 + 2x - 4)
3(x^2 + 2x - 4) + 1
3x^2 + 6x - 12 + 1
3x^2 + 6x - 11
