Answer:
Step-by-step explanation:
There is only one figure in the attached image and the solution (surface area) is as follows:
The shape can be sub-divided into:
1. Rectangle
Dimension: 40 by 35
2. Rectangle
Dimension: 40 by 28
3. Rectangle
Dimension: 21 by 40
4. 2 triangles
Base: 21 and Height: 28
Calculate area of each and add them up to get the surface area of the figure.
1. Rectangle
Dimension: 40 by 35
2. Rectangle
Dimension: 40 by 28
3. Rectangle
Dimension: 21 by 40
4. 2 triangles
Base: 21 and Height: 28
So, the area is:
Factor out 40
Answer: x = 2/3 and y = 2/3
Step-by-step explanation:
I've attached the solution.
From the solution, you get y = -5x + 4 and
y = x.
Now,
Put y = x in y = -5x + 4.
x = -5x + 4
6x = 4
x = 4/6
x = 2/3
So, y = 2/3 because y = x.
