Answer:
218
Step-by-step explanation:
first find the area of the circle-

to find the area of the triangle, we need the base and the height. The base we know is 16, since we don't know the height yet, use the Pythagorean theorem to find the height. One leg is 16 the hypotenuse is 20 (2* the radius).

Now I know the height is 12. Find the area of the triangle

subtract the area of the triangle from the area of the circle
314-96=218
Answer:
8 grams
Step-by-step explanation:
The balance is in equilibrium, so the weights of the two sides are equal.
Let the weight of a square be s.
Left side: 2s + 4
Right side: s + 3(4) = s + 12
The weights are equal, so we set the two expressions equal.
2s + 4 = s + 12
s = 8
Answer: The weight of a square is 8 grams.
X=1 and y=-2
In ordered pairs it would be (1,0) and (0,-2)
