Answer:

B. 5

Step-by-step explanation:

I. If g(x) = 3 - 2x and g( -1 )

    g(-1 ) => inside x value is -1

II. Solve by replace x.value with -1

      g(-1 ) = 3 - 2(-1)

               = 3 + 2

       g(-1 ) = 5

Hope that help :)

Answer:

g(-1)=5

Step-by-step explanation:

Put value of x, which is - 1

g(x) = 3 - 2x \\ g( - 1) = 3 - 2( - 1) \\ g( - 1) = 3 + 2 \\ g( - 1) = 5

area=legngth tiimes width
legnth is 10 more than 2 times width
l=10+2w
lw=area=(10+2w)w=10w+2w^2
area=3600
3600=10w+2w^2
so divide by 2
1800=5w+w^2
subtract 1800 from both sides
(note they used x instead of w)
0=w^2+5w-1800
then the facotred form is (w-40)(w+45)=0

0 product property measn if you have xy, then x and or y =0

therefor
w-40=0 and w+45=0
w=40 or -45
discard negative because negative legnth is not possible


explian how solution relates to situation
it is math so it is correct because we represented it corrrectly


the other solution is because of math and eliminate negative legnth becasue tha tis not possible
basically because we represented it correctly
not a very clear quetion to answer

basically 'because it represents the solution so we solved it and it is correct'
