Answer:
13
Step-by-step explanation:
a^2 + b^2 = c^2
5^2 + 12^2 + c^2
25 + 144 = c^2
169 = c^2
<em>Square root both sides</em>
c = 13
Answer:(2x + 9i)(2x - 9i)
Step-by-step explanation:
a^2 - b^2 = (a+b)(a-b)
a^2 + b^2 = (a+bi)(a-bi) = a^2 + abi - abi - b^2 i^2
But -b^2 i^2 = +b^2
The answer would be 1/4 as u take 25 4 times it would equal 100.
60 sec = 1 min
176 x 60 = 10, 560
