Use Pythagorean theorem.
[tex]|ON|^2+|MN|^2=|OM|^2\\\\x^2+x^2=8^2\\\\2x^2=64\ \ \ \ |divide\ both\ sides\ by\ 2\\\\x^2=32\to x=\sqrt{32}\\\\x=\sqrt{16\cdot2}\\\\x=\sqrt{16}\cdot\sqrt2\\\\\boxed{x=4\sqrt2}
Answer: |MN| = 4√2.
Answer:

Step-by-step explanation:
Answer:
138
Step-by-step explanation:
70 + 32 = 102
102 + 36 = 138
138 + 40 = 178
178 + 44 = 222
Answer:
The answer is 18
Step-by-step explanation:
Substitute b for -3 and y for 5 so 3*5=15
You then subtract -3 from 15 so a negative minus a negative is a positive so the equation would be 3*5=15--3= 3*5=15+3=18
(x + 7) - (3x + 4)=
x + 7 - 3x - 4 =
-2x + 3
