To fond the area of a trapezoid, add the top and bottom together, divide that by 2, than multiply by the height.
Area = (8+12)/2 = 20/2 = 10
10 x 9 = 90 square centimeters.
Answer:
x = 1/15
Step-by-step explanation:
Answer:
2
Step-by-step explanation:
It rose 8 and ran 4 and slope is rise over run.
8/4 = 2
Answer:
b
Step-by-step explanation:
Answer:
The coordinates of the intersection point are 
Step-by-step explanation:
we have
-----> equation A
-----> equation B
-----> equation C
we know that
If the system of equations intersect at one point, then the system of equations has one solution
using a graphing tool
see the attached figure
The coordinates of the intersection point are 
This point is a common solution for the three equations
Verify
Substitute the value of
in each equation
so
Equation A

----> is true, therefore the point is a solution of the equation A
Equation B


----> is true, therefore the point is a solution of the equation B
Equation C

----> is true, therefore the point is a solution of the equation C
