C because a rectangle has 4 lines of symmetry
First, I'd simplify this problem by dividing every term by 2:
x^4 - 4x^3 + 5x^2 - 4x + 4 = 0
Then I'd think of the possible factors of that constant term, 4: They would be plus or minus 1, plus or minus 2, or plus or minus 4.
Let's try x = -4 as a possible root. Setting up and using synthetic division:
____________________
-4 / 1 -4 5 -4 4
-4 32
----------------------------
1 -8 37
This result is not helpful. So, try the possible root +4 instead:
________________
+4 / 1 -4 5 -4 4
4 0 20 64
----------------------------
1 0 5 16 68 4 is not a root because the remainder
(68) is not zero.
Try x = 2:
________________
+2 / 1 -4 5 -4 4
2 -4 2 -40
----------------------------
1 -2 1 -2 0
2 is a root because the remainder is zero.
Continue this process until you've found the other 3 roots.
Hint: Try the possible root x = -2 with the following coefficients:
____________
-2 / 1 -2 1 -2

Find the mode of this data set:<br>
31, 30, 32, 31, 30, 31, 32,<br>
33, 30, 31, 31, 30, 32

Answer:
31 is the mode of the data as it appears 5 times
Answer:
F
Step-by-step explanation:
b = 3 5/8 × x < -- Times
x is a variable that uses for the representation of the number of pies
Example : 3 pies there
b = 3 5/8 × 3
therefore b = 5.625 pounds
Answer:
d I believe
Step-by-step explanation:
so they take away certain blocks and they never replaced the 2 lines
