Answer:
x² - 2x + 1
Step-by-step explanation:
We want to express (x - 1)² as a trinomial. In other words, we want to expand this out.
(x - 1)² = (x - 1)(x - 1)
We use FOIL (First, Outer, Inner, Last). The First terms are x and x. Multiply:
x * x = x²
The outer terms are x and -1. Multiply:
x * (-1) = -x
The inner terms are -1 and x; multiply:
(-1) * x = -x
The last terms are -1 and -1; multiply:
(-1) * (-1) = 1
Add all these together:
x² + (-x) + (-x) + 1 = x² - 2x + 1

Answer:
0.45 = 9/20
0.88 = 22/25
Step-by-step explanation:
Answer:
Option C is false
It is true that the square of both 10 and -10 is 100 but you can still obtain 100 by squaring 5 so the third option is incorrect
The answer is yes, but how to show it. Use the formula
Suppose you go from 40 degrees Fahrenheit to 41 degrees Fahrenheit
The degrees C for 41o F degrees is C = 5/9(F - 32) = 5/9(41 - 32) = 5o C
The degrees C for 40o F degrees is C = 5/9(F - 32) = 5/9(40- 32) = 4.44
The difference is 0.555555
What this means is that for every degree Fahrenheit, the Celcius amount of degrees is a little over 1/2 a degree. the 5/9 should give you the clue you need.
Now here's where you need to put your thinking cap on. Which one is bigger? If you move up one degree on one scale and only 1/2 a degree on the other, Isn't the one that moved only 1/2 a degree the larger measurement?
