Answer:

Surface area of the rectangular prism = 234\,mm^2

Step-by-step explanation:

The surface area of the rectangular prism is:

=2((Length\times Width)+(Width\times Height)+ (Height\times Length))

Length=15\,mm\\ \\Width=3\,mm\\\\Height=4\,mm

Area is:

   =2((15\times 3)+(3\times 4)+ (4\times 15))\\\\=2(45+12+60)\\\\=2(117)\\\\=234\,mm^2

Surface area of the rectangular prism is: 234\,mm^2

Answer:

see below

Step-by-step explanation:

24 - 3 x = -27

Subtract 24 from each side

24-24 - 3 x = -27-24

-3x =-51

Divide each side by -3

-3x/-3 = -51/-3

x = 17

Check

24 -3(17) = -27

24 -51 = -27

-27 = -27

Step-by-step explanation:

We can turn these into equations by making the shirts 's' and the ties 't'.  

4s+2t=95 and 3s+3t=84

Now we can solve the system of equations with substitution.

Answer:

351.68 cm^2

Step-by-step explanation:

We need to find the area of the frame itself. the radius of the inner circle is 12, but the frame has a radius of 4. You add 12 and 4 and you get 16. The formula for area of a circle is A=πr^2. So A= 3.14 x16^2. Then you have A= 3.14x 256 and you get 803.84. But we only want the area of the frame, so you have to get the area of the inner circle and subtract. You get A= 3.14 x 12^2. 3.14x144 is 452.16. 803.84-452.16 is 351.68. Hope this helped. :)
