Answer:
x=-11, y=-5. (-11, -5).
Step-by-step explanation:
2y=2x+12
y=-2-3
-----------------
simplify 2y=2x+12 into y=x+6
y=-5
------------------
-5=x+6
x=-5-6=-11
Area= 1/2(height)×(base↓1+base↓2)
Area=1/2(3)×(8+11)
Area=1/2(3)×(19)
Area=1/2(57)
Area=57/2 OR 28.5
Thus, the area of the trapezium is 28.5inches^2
Answer:
A: radius of the sphere
Step-by-step explanation:
The formula for surface area is A = 4πr^2
With r being the radius and A the surface area.
For volume it is
V= (4/3)πr^3
Answer:
C
Step-by-step explanation:
This triangle has a right angle so it is right.
It also has three different sides so it is scalene.
C is the answer
