Answer:

y= 2

x= 0

Step-by-step explanation:

okay your going to substitute -y+2 for x in the other equation

so it be 3y+(-y+2)=6

combined like terms and get 2y+2 = 6

subtract 2 by both sides and divide 2 from both to get y= 2

now plug y= 2 into the first equation to get x

x = -2 +2

Find the surface area of the triangular prism.
Ivahew [28]

The surface area of the triangular prism is 93 squared feet.

<h3>What is the surface area of the triangular prism?</h3>

The surface area of triangular prism is expressed as;

S.A = bh + ( s₁ + s₂ + s₃ )H

From the diagram;

  • h = 2ft
  • b or s₁ = 3ft
  • s₂ = 3ft
  • s₃ = 3ft
  • H = 10ft

We substitute our given values into the equation above.

S.A = bh + ( s₁ + s₂ + s₃ )H

S.A = (3ft × 2ft) + ( 3ft + 3ft + 3ft )10ft

S.A = 3ft² + ( 9ft )10ft

S.A = 3ft² + 90ft²

S.A = 93ft²

The surface area of the triangular prism is 93 squared feet.
