Answer:
x=
Step-by-step explanation:
For this problem, you need to know the Pythagorean Theorem, which is A²+B²=C².
- First, write down what you know. You need to find the longest side, which is x. The other sides are 8 and 7.
- To solve, you need to plug in A with 8 and 7 with B.
- Now solve:
- 8²+7²=C²
- 64+49=C²
- 113=C²
- =C
2x-y=6 2x-y=6
x+y=36 2(36-y)-y=6
72-2y-y=6
x+y=36 72-3y=6
-y -y -72 -72
x=36-y <u>-3y=66</u>
x=36-22 -3y -3y
<em>x=14 y=22</em>

Answer:
12-2(n-1).
Step-by-step explanation:
It can be written 12-2n+2=14-2n, so that when n=1, the 1st term is 14-2=12. The 5th term is 14-10=4; the 6th is 14-12=2.
