Surface area : The area of the surface of the figure.
We will find the area of each separate figure, then add them al up:
Triangle: (3*4) / 2 = 6
For 2 triangles the surface area will be 12.
Square: 3*3 = 9
Rectangle One: 4*3= 12
Rectangle two: 5 * 3 = 15
Now we add them all up:
12 + 9 +12 + 15 = 48
So the surface area is 48 cm^2

Answer:
It was an increase of 200%.
Step-by-step explanation:
In order to identfy the percent of the change we need to first find the absolute value, to do that we subtract the final value from the initial one. We have:
absolute difference = 36 - 12 = 24 inches
Since this value is positive it was an increase. Now we need to find the percentage at which it was increased, to do that we can use a rule of three in a way that the original value is 100% and the value we want to know is the percentage for the absolute increase. We do this as follows:
12 inches -> 100%
24 inches -> x %
12*x = 2400
x = 2400/12 = 200 %
It was an increase of 200%.
Part A:
We observe that we have the following system of equations:
y = 4x
y = 2x-2
The solution to the system of equations is an ordered pair (x, y), that is, a point in common that both functions have.
Part B:
x y = 4x y = 2x-2
-3 -12 -8
-2 -8 -6
-1 -4 -4
0 0 -2
1 4 0
2 8 2
3 12 4
The solution is the ordered pair:
(x, y) = (-1, -4)
Part C:
