Area = 1/2 x base x height
Area = 1/2 x 9 x 4
Area = 9 x 2
Area = 18 cm^2
Answer:
x=3, y=-2. (3, -2).
Step-by-step explanation:
4x+2y=8
5x+3y=9
---------------
simplify 4x+2y=8 into 2x+y=4
-----------------
2x+y=4
5x+3y=9
----------------
y=4-2x
5x+3(4-2x)=9
5x+12-6x=9
-x=9-12
-x=-3
x=3
2(3)+y=4
6+y=4
y=4-6
y=-2
so what was the question again?
Answer:
Step-by-step explanation:
First we need to understand what is collinear and coplanar . Points that are on same plane are known as coplanar and points that are on same line are known as collinear .
Here , RLS are on the same plane but they are not on the same line . So the given three points are coplanar but not collinear .
Therefore the correct option is A.
Answer: 46
Step-by-step explanation:
The angles add to form a straight angle, so x+99+35=180. It follows that x=46.
