(X+3)^2+(y-2)^2= 16
The formula is (x-h)^2+(y-k)^2=r^2
Answer:
A
Explanation:
If you graph the points and connect them, you'll see the triangle they're asking about. Yhe base of the triangle is 9 and the height is 8. The area of a triangle is half of the base times the height. So multiply 8 by 9 and you get 72. This is twice the area. So divide it by 2 and you get 36, which is the area of the triangle. So the answer is A.
Answer:
w = 2.5 cm
Step-by-step explanation:
The area (A) of the triangle is calculated as
A = 
bh ( b is the base and h the height )
Here b = 5 and h = 6, thus
A = 0.5 × 5 × 6 = 15 cm²
Thus the area of the rectangle is 15 cm²
A = lw ( l is the length and w the width )
Here l = 6 and w is to be found
6w = 15 ( divide both sides by 6 )
w = 2.5 cm
The cube root of 1728 is 12inches. To find the volume of a cube you take one length and then cube it. Do the opposite with the volume to get a side length.
