Ok what you do it you start at 0 and you go up 13 place a point there then go up 3 and 1 to the right and place a point there then you go back to your first point and go down 3 and to the left 1 and place a point there then put a line through the points...
SORRY IF CONFUSED!!!
Answer:
Area of triangle formula:
A = b*h/2
B is 18 and h is 13
B is base and h is height.
18 * 13 is 234.
We must divide by two because just multiplying the two numbers would result in an area of a square, divide by 2 for a triangle.
234/2 =
117 km²
Answer:
15
Step-by-step explanation:
15f-60=15×5-60=75-60=15
A: 100m^2
10 x 10 = 100
B: 28.274m^2
You have to do pi x r squared
So,,,
Pi x 3^2
9pi = 28.274....
C: just subtract the grass bed from the land...
100 - 28.274 = 71.72566612...
So C is 71.726m^2
Hope this helped! Have a nice day :)
x = - 
- 4x - 25 = 8x + 15
subtract 8x from both sides
- 4x - 8x - 25 = 15
- 12x - 25 = 15
add 25 to both sides
- 12x = 15 + 25 = 40
divide both sides by - 12
x =
= -
