Answer:
1/60
Step-by-step explanation:
Answer:
r = - 7, r = - 5
Step-by-step explanation:
Given
r² = - 12r - 35 ( add 12r to both sides )
r² + 12r = - 35
To complete the square
add ( half the coefficient of the r- term )² to both sides
r² + 2(6)r + 36 = - 35 + 36
(r + 6)² = 1 ← take the square root of both sides )
r + 6 = ± 1 ( subtract 6 from both sides )
r = - 6 ± 1, thus
r = - 6 - 1 = - 7 or r = - 6 + 1 = - 5
Answer:
40 I told u
Step-by-step explanation:
right angles are 90 degrees
121.5
121.5 rounded to nearest whole number is 122 --> 121.49 rounded to the nearest whole number is 121
9,000 or (9×1,000) either one can be the answer
