Answer:No
Step-by-step explanation:
Given system of equation is:
2x + 3 = y
2x + y = 15
To check whether (2,7) is solution to this system or not, we will put x=2 and y=7 in both equations.
Putting x=2 and y=7 in Eqn 1
2(2) + 3 = 7
4 + 3 = 7
7 = 7
Thus the ordered pair satisfies the equation
Putting x=2 and y=7 in Eqn 2
2(2) + 7 = 15
4 + 7 = 15
11 ≠ 15
The ordered pair do not satisfy the second equation.
Hence,
(2,7) is not a solution to the given system of equations.

Answer:
Area of a rectangle is Width * Length
Apply this to each area the question asks for
AreaTop = 8cm * 4cm = 32
AreaBottom = the same, 32
AreaFront = 2cm * 4cm = 8
AreaBack = the same, 8
AreaLeftSide = 2cm * 8cm = 16
AreaRightSide = the same, 16
TotalSurfaceArea = 16 + 16 + 8 + 8 + 32 + 32 = 112
