Answer:
Given the equations:
.....[1]
....[2]
Substitute the value of x in [1] we get;'
Use identity:
Combine like terms;
Subtract 36 from both sides we get;
By zero product property, we get;
y = 0 and
Substitute these y values in [2] to get x values;
For y = 0 we have;
x = 2(0) +6 = 0+6 = 6
For x = -4.8
x = 2(-4.8)+6 = -9.6 + 6 = -3.6
Therefore, the solution for the given equations are; (6, 0) and (-3.6, -4.8)
Answer:
Step-by-step explanation:
You need to remember the following:
1. The area of a rectangle can be calculated with the following formula:
Where "l" is the length and "w" is the width.
2. The area of a triangle can be calculated with the following formula:
Where "b" is the base and "h" is the height.
Use those formulas to find the area of each face.
<u> Area of the rectangle</u>
<u>Area of two triangles</u>
There are two equal triangles. Each one has a base of 10 inches and a height of 5 inches. Then, their areas are equal:
The areas of the other two triangles (which are equal) are:
Adding the areas of the faces, you get that the surface area of the rectangular pyramid is:
