x+90=180
x=90
Answer:
x=4,y=9
Step-by-step explanation:
We want to solve the equation:
simultaneously.
Multiply the top equation by 3 and the bottom equation by 2 to get:
6y-15x=-6
6y+4x=70
Subtract the top equation from the bottom equation.
We substitute x=4 into 2y-5x=-2 to get:
Therefore the solution to the system is
(4,9)
Consider ΔAQD. This triangle has the area
where H is the heigh drawn from the point Q to the side AD.
Note that the height H is also the height of the parallelogram. So the area of the parallelogram ABCD is
From these two statements you can conclude that
Now consider ΔDMQ. The ratio between the area of triangles DMQ and AQD is
Since you have that
and
Thus,
Answer: correct choice is B
Answer:
x(x-2)
Step-by-step explanation:
x^2−2x
Factor out an x
x(x-2)
This is not a special product
