Answer:
18
Step-by-step explanation:
Y = x + 5
y = -5x -1
so than you make y = y so x + 5 = -5x -1 result 6x = -6 so x = -6/6 so x = -1
and than you check it
y = - 1 +5 = 4
and
y = - 5 *(-1) -1 = 5 -1 = 4
so this mean that - 1 is the solution of the system sure

Answer:
234 cm²
Step-by-step explanation:
Given expression to represent the surface area of the rectangular prism is
The given value of x is 3.
Now, finding value of expression by sustituting value of "x" as given.
Surface area of the rectangular prism =
Surface area of the rectangular prism=
∴ Surface area of the rectangular prism=
Surface area of the rectangular prism=
∴ Surface area of the rectangular prism= 234 cm²
600 becuase 90/.30= 300 and 300*2 =600
