Answer:

See below

Step-by-step explanation:

Okay so...I might be interpreting the question wrong-if I am please comment! I'll fix it to the best of my ability.

A) Plug in -5 to all x values

   f(-5)=10(-5)-3

          ==50-3

    f(-5)= -53

B) f(0)=10(0)-3

    f(0)= -3

C) f(7)=10(7)-3

         =70-3

    f(7)=67

D) f(t^2+2)=10(t^2+2)-3

                 =10t^2+20-3

     f(t^2+2)=10t^2+17

E) f(12-x)=10(12-x)-3

              =120-10x-3

    f(12-x)=117-10x

F) f(x+h)=10(x+h)-3

             =10x+10h-3

Answer:

Total = 166cm^2

Step-by-step explanation:

Given

See attachment

Required

Determine the surface area

The figure is made up of two cuboids and the surface area of a cuboid is:

Area = 2LB + 2LH + 2BH

Because the bottom part of the upper piece is not visible, the area is calculated as:

Area = 2LB + 2LH + BH

This gives:

Area = 2 * 5*4 + 2 * 4 * 2 + 5 * 2

Area = 66

For the bottom piece:

We calculate its area as Area = 2LB + 2LH + 2BH. However, the area of the invisible part will be subtracted.

So, we have:

Area = 2*3*5 + 2*3*5 + 2*5*5 - 2*5

Area = 100

The total surface area is:

Total = 66 + 100

Total = 166cm^2

timurjin [86]
The multiply choice were worth 4 points. 
Gretchen= 18x+19
Ezia= 15x+31

So basically you can enter any number. At first I picked 3 and then I did the math and I got 73 points for Gretchen and 76 points for Ezia. 

Then I pick four and then I got 91 points for them both. This is how I got the answer: 

18x+19=15x+31
18(4)+19=15(4)+31
72+19=60+31
91=91
