the lateral area and total area of regular pyramid with a square base is 130
Answer: 222cm
Step-by-step explanation:
To find the area of this composite shape you will have to split them into 2 shapes; a rectangle and a triangle.
To work out the area of the rectangle you have to do 15×12= 180
Then, to work out the area of the triangle, you use the formula base times height divided by 2.
7×12=84
84÷2=42
Then to work out the total area of both the rectangle and the triangle, you have to add the area of both.
180+42=222cm
Hope this helps :)

Remember that the slope intercept formula is:
y = mx + b
m is the slope
b is the y-intercept
First let's find the slope (m)
The formula to find slope using two points is
In this case...
^^^Plug these numbers into the formula for slope...

-2
^^^This is your slope
Here is what we have so far for the slope intercept formula:
y = -2x + b
Now we must find b
To do that you must plug in a point the line goes through in the x and y of the equation, then solve for b
For this explanation we will use the point (0,4) although you could also do it with point (3, -2) and you should get the same answer
4 = -2(0) + b
4 = 0 + b
4 = b
NOTE: For this particular problem you wouldn't technically need to go through the steps above to find b. In this case one of the points given, (0, 4) is already the y-intercept of the line (b)
y = -2x + 4
Hope this helped!

Answer:
3, 4, -7
Step-by-step explanation:
Coefficients are the numbers in front of the variable.
1 < 15 - 2a < 7. That is the answer
