Answer:

264

Step-by-step explanation:

f(x)=2x^2+3x-5

g(x)=x+9

(fg)(x)=f(x) \times g(x)

\implies (fg)(x)=(2x^2+3x-5)(x+9)

(fg)(3)=(2(3)^2+3(3)-5)(3+9)

\implies (fg)(3)=22 \times 12

\implies (fg)(3)=264

Answer:

Correct option is (C)

Step-by-step explanation:

we are given that -Tim design a pair of shorts,S, and T-shirts,t.

Tim sell Sorts for $12 and T-shirts for $8 each.

Tim can work atmost 18 hours a day so we can write time\leq 18

Time taken to design a T-shirt is 30 minutes and for Shorts, it is 45 minutes.

\frac{30}{60}t+\frac{45}{60}s\leq   18\\\text{Multiply both the sides by 60}\\30t+45s\leq 1080\\\text{Divide both the sides by 45}\\s+0.66t\leq 24\\\text{Subtract 0.66t from both the sides}\\s\leq 24-0.66t

He must design 12 itesm each day, so we can write t+s\geq 12

Further it can be written as

t+s\geq 12\\\text{Subtract t from both the sides}\\s\geq 12-t

Also Tim can not design more than 30 items in one day, so we can write

t+s\leq 30\\\text{Subtsract t from both the sides}\\s\leq 30-t

Hence from the above equations , its claer that

s\geq 12-t,s\leq 30-t,s\leq 24-0.66t,s\geq 0,t\geq 0
