Answer:
(2, - 2 )
Step-by-step explanation:
y = - 3 + x → (1)
3x + 2y = 2 → (2)
Substitute y = - 3 + x into (2)
3x + 2(- 3 + x) = 2 ← distribute parenthesis and simplify left side
3x - 6 + x = 2
4x - 6 = 2 ( add 6 to both sides )
4x = 8 ( divide both sides by 4 )
x = 2
Substitute x = 2 into (1)
y = - 3 + (2) = - 3 + 1 = - 2
solution is (2, - 2 )
A = 2(6)(8)/2 + 8(7) + 7(10) + 6(7)
A = 146 sq m
Therefore the surface area of the triangular prism is 146 m^2.
