Find the surface area of the prism.
2 in.
7
in.
The surface area is
square inches

64in^2  rectangular prism

32in^2 = slope triangular prism

Step-by-step explanation:

If it is rectangle square faced prism the area is found multiplying the rectangle first = 7 x 2 = 14in^2 x 2 = 28in^2 + 28in^2 = 56in^2 + the square faces 2 x 2 x 2= 8in^2

= 56+ 8 = 64in^2  

If it is slope prism we half this = 34in^2

27/4x^6 y^8

step-by-step explanation:

4(3x^2y^4)^3 (2x^3y^5)^4

=

108x^6 y^12 /16x^12 y^20

=

108 /16x^6 y^8

=

27 /4x^6 y^8

answer: they are supplementary angles

step-by-step explanation: 161+19=180. supplementary angles equal 180 degrees
