63 + 55 = 118
360- 118 = 242
<span>k^2+11k has 11 as the coefficient of the first power of the variable (k).
To complete the square:
Take HALF of this coefficient. In other words, take HALF of 11, obtaining 11/2.
Square this (11/2): (121/4)
Add this 121/4 to </span><span>k^2+11k
Result: </span><span>k^2+11k + 121/4
This is a perfect square: </span>k^2+11k + 121/4 = (k + 11/2)^2
Answer: The number to be added to k^2 + 11k to make it a perfect square is (121/4).
Just do the amount (909) times 0.063 %
Answer:
13.3
Step-by-step explanation:
f² = e² + g² - 2egcos(F)
f² = 9² + 18² - 2(9)(18)cos(46)
f² = 175.8974029
f = 13.26263128
The answer is 73567374 so even
