Answer:
Hey there!
15 is composite. A composite number has factors other than one and itself. 15 has factors 3 and 5.
Thus, 15 is composite.
Let me know if this helps :)
simplify
n-2 = 10n/2 + 4/2
n-2 = 5n + 2
subtract 5n to both sides
n - 2 - 5n = 5n + 2 - 5n
simplify
-4n - 2 = 2
add 2 to both sides
-4n - 2 + 2 = 2 + 2
simplify
-4n = 4
divide both sides by -4
-4n/-4 = 4/-4
simplify
n = -1
hope it helps
Step-by-step explanation:
Equation for circle centered at origin:
x² + y² = r².
Therefore r² = (-4)² + (-2)² = 20, r = √20.
Hence d = 2r = 2√20 = 8.94 (2d.p.)
Answer:
No, because the 3 angles of a triangle must add up to 180 degrees and yours only add up to 55

Answer:
8.86
Step-by-step explanation:
Im guessing you want the rectangles area
Finding circle area do radius times radius times 3.14 so 1 x 1 = 1 x 3.14 = 3.14
Rectangle area is length times width so 3 x 4 = 12 - 3.14 = 8.86
