So first we need to figure out the area of the lawn:

Area= l*w
A= 25*30 =750

This means that one bag of fertilizer will only cover about 1/7 of the entire thing so we will need 8 bags of fertilizer because
750/100 = 7.5 but since you can't have half a bag of fertilizer you round up to 8.

Answer:

f+g(2)=10

f-g(4)=-4

F/G(2)= 7/3

(f)(g)(1)=0

Step-by-step explanation:

1. (f+g)=2x+3+x^2-1 2(2)+2=10

2. (f-g)=(2x+3)-(x^2-1)=-x^2+2x+4= -16+8+4=-4

3. f/g= 2x+3/x^2-1 4+3/3= 7/3

4. f*g= (2x+3)(x^2-1)= 2x^3+3x^2-2x-3= 2(1)^3-2(1)+3(1)^2-3=0
