Answer:
30 cm^2
Step-by-step explanation:
a = 13 cm
b = 12 cm
using Pythagorean theorem:
a^2 = b^2 + c^2
--> c^2 = a^2 - b^2 = 13^2 - 12^2 = 169 - 144 = 25
--> c = √25 = 5
The area of that right triangle is:
S = b.c / 2 = 12 . 5 / 2 = 30 (cm^2)
3m because in a square all sides are the same and there are 4 sides, so 12 ÷ 4 = 3
-14,-10,-6,-2,2,6
Answer by Mimiwhatsup: I could easily subtract -14 from -10 to find out the sequence so they are adding four each time. That means the pattern will continue going on like this 10, 14, 18, 22 and so forth.
I probably did this wrong but i think its 21780.....cause i timed an acre by 1/2 to get that answer <span />
