1. Calculate how many hours passed between her temperature checks. 8 p.m to 8 a.m. is 12 hours.
2. Calculate the total change in temperature. 36 - 54 is -18, so the temperature went down by 18 degrees.
3. We are looking for degrees per hour, so we put derees(18) over hours (12) to get 18/12.
4. Calculate by dividing. The answer is 1.5 degrees per hour.

<span>Trinomial Ax^2 + Bx + C is perfect square if:
A > 0
C > 0
B = ±2√A√C
36b^2 − 24b − 16
C < 0
4a^2 − 10a + 25
2√A√C = 2*2*5 = 20,
B = −10
16x^2 + 24x − 9
not perfect square,
C < 0
4x^2 − 12x + 9
perfect square:
A>0,
C>0,
2√A√C
= 2*2*3
= 12
= -B
= (2x − 3)^2

Step-by-step explanation:
9.9²
(10-0.1)²
= 10² -2 (10) (0.1) + 0.1²
= 100 -2 + 0.01
= 98.01
