Answer:

The value of (f-g)(2)= 14

Step-by-step explanation:

 f(x) = 3x^2 + 1 and g(x) = 1 – x

we need to find the value of (f-g)(2)

(f-g)(x)= f(x) - g(x)

Replace f(x) and g(x)

(f-g)(x)= f(x) - g(x)= (3x^2+1 -(1-x))=  3x^2+1-1+x= 3x^2+x

Now plug in 2 for x

(f-g)(x) =3x^2+x

(f-g)(2) =3(2)^2+2=12+2=14

The value of (f-g)(2)= 14

The perimeter of rectangle is 48 cm. Find the sides of the rectangle if one of the sides is 12 cm longer than the other.
natima [27]
L=W+12
2L+2W=48
2(W+12)+2W=48
2W+24+2W=48
4W=48-24
4W=24
W=24/4
W=6 ANS. FOR THE WIDTH.
L=6+12=18 ANS. FOR THE LENGTH.
PROOF:
2*18+2*6=48
36+12=48
48=48
