Answer:
c = 121
Step-by-step explanation:
Given
t² - 22t
To complete the square
add ( half the coefficient of the t- term )² to t² - 22t
= t² + 2(- 11)t + (- 11)²
= t² - 22t + 121
with c = 121
Thus
t² - 22t + 121 = (t - 11)²
5x<12
Five times x is equally 5x fewer than is equally < # 5x<12
Answer: 610
311≈310 298≈300
310+300=610
-569
