I believe it’s 3.5 I’m not sure!
-10.35°
Add each temperature and then divide by four to find the average.
-12.1 -7.8 - 14.3 -7.2 = -41.4
-41.4 ÷ 4 = -10.35
Answer: 6 11/12
Step-by-step explanation:
Answer:
x = 5
Step-by-step explanation:
3x + 6 = 21
3x = 21 - 6
3x/3 = 15/3
x = 5
The answer would be A: (x-3)(x-3)
Explanation: (X-3)(X-3) would create three new numbers: x^2, -6x, and 9,
(-6x is created because x*-3 + x*-3 = -3x + -3x, or -6x)
9, as you know, is 3*3 or -3*-3
