2980 round everything to the nearest tens and add with your head to get it
X^2 + 10x + c
Use the number in front of x, (10), to help you.
First, divide 10 by 2:
10/2 = 5
Second, square the answer, (5).
(x+5)(x+5) = 25
Answer: c=+25
Answer:
d. -4
Step-by-step explanation:
- 4p – 12 = 8 + 4p + 5p
- 4p – 12 = 8 + 9p
- 4p – 9p = 8 + 12
- – 5p = 20
- p = 20 ÷ (– 5)
- p = – 4
The average score for the entire year is 88.44444, so by rounding down the answer is 88%
