Answer:
4 possible real zeroes
solutions are
[tex]x=\sqrt{3}\\x=-\sqrt{3}[/tex]
x = 1
x = -1
Step-by-step explanation:
4th order polynomial therefore there are 4 possible solutions.
factoring it:
(x^2-3)(x^2-1)
Solve for x
x^2 - 3 = 0
x^2 = 3 ; take the square root of both sides
[tex]x=\sqrt{3}\\x=-\sqrt{3}[/tex]
x^2 - 1 = 0
x^2 = 1
x = 1
x = -1

Answers
Complete Question
Which division problem does the model show? 3 fraction bars. The bars are labeled 1 and each has 3 boxes underneath labeled one-third.
a) 3 divided by one-third = 9
b)3 divided by two-thirds = 9
c) 9 divided by one-third = 3
d) 9 divided by two-thirds = 3
Answer:
a) 3 divided by one-third = 9
Step-by-step explanation:
We are told in the question that:
3 fraction bars. The bars are labeled 1 and each has 3 boxes underneath labeled one-third.
The division problem does the model shows from the description above is calculated as:
3 fraction bars ÷ 1/3
= 3 ÷ 1/3
= 3 × 3
= 9
Hence:
Option a) 3 divided by one-third = 9 is the correct option.
Answer:
3rd one is correct

What is the value of x in the equation 3(x + 10) = 4(x − 2)?
Answers
Answer:
3x+30=4x-8
-x=-38

Final Answer: [tex]x = 38[/tex]
Steps/Reasons/Explanation:
Question: What is the value of x in the equation [tex]3(x + 10) = 4(x - 2)[/tex]?
Step 1: Expand.
[tex]3x + 30 = 4x - 8[/tex]
Step 2: Subtract [tex]3x[/tex] from both sides.
[tex]30 = 4x - 8 - 3x[/tex]
Step 3: Simplify [tex]4x - 8 - 3x[/tex] to [tex]x - 8[/tex].
[tex]30 = x - 8[/tex]
Step 4: Add [tex]8[/tex] to both sides.
[tex]30 + 8 = x[/tex]
Step 5: Simplify [tex]30 + 8[/tex] to [tex]38[/tex].
[tex]38 = x[/tex]
Step 6: Switch sides.
[tex]x = 38[/tex]

divide 123 by 13 with remainder
Answers
Answer:
9 Remainder 6
Step-by-step explanation:
Step 1:
Start by setting it up with the divisor 13 on the left side and the dividend 123 on the right side like this:
1 3 ⟌ 1 2 3
Step 2:
The divisor (13) goes into the first digit of the dividend (1), 0 time(s). Therefore, put 0 on top:
0
1 3 ⟌ 1 2 3
Step 3:
Multiply the divisor by the result in the previous step (13 x 0 = 0) and write that answer below the dividend.
0
1 3 ⟌ 1 2 3
0
Step 4:
Subtract the result in the previous step from the first digit of the dividend (1 - 0 = 1) and write the answer below.
0
1 3 ⟌ 1 2 3
- 0
1
Step 5:
Move down the 2nd digit of the dividend (2) like this:
0
1 3 ⟌ 1 2 3
- 0
1 2
Step 6:
The divisor (13) goes into the bottom number (12), 0 time(s). Therefore, put 0 on top:
0 0
1 3 ⟌ 1 2 3
- 0
1 2
Step 7:
Multiply the divisor by the result in the previous step (13 x 0 = 0) and write that answer at the bottom:
0 0
1 3 ⟌ 1 2 3
- 0
1 2
0
Step 8:
Subtract the result in the previous step from the number written above it. (12 - 0 = 12) and write the answer at the bottom.
0 0
1 3 ⟌ 1 2 3
- 0
1 2
- 0
1 2
Step 9:
Move down the last digit of the dividend (3) like this:
0 0
1 3 ⟌ 1 2 3
- 0
1 2
- 0
1 2 3
Step 10:
The divisor (13) goes into the bottom number (123), 9 time(s). Therefore put 9 on top:
0 0 9
1 3 ⟌ 1 2 3
- 0
1 2
- 0
1 2 3
Step 11:
Multiply the divisor by the result in the previous step (13 x 9 = 117) and write the answer at the bottom:
0 0 9
1 3 ⟌ 1 2 3
- 0
1 2
- 0
1 2 3
1 1 7
Step 12:
Subtract the result in the previous step from the number written above it. (123 - 117 = 6) and write the answer at the bottom.
0 0 9
1 3 ⟌ 1 2 3
- 0
1 2
- 0
1 2 3
- 1 1 7
6
You are done, because there are no more digits to move down from the dividend.
The answer is the top number and the remainder is the bottom number.
Therefore, the answer to 123 divided by 13 calculated using Long Division is:
