What are the terms in x - 53 - 4x - w + 6x + 8
Answer:
3x, -45, -w
Step-by-step explanation:
We want to simplify this expression to find which terms there are.
x - 53 - 4x - w + 6x + 8
We can group the x's, w's and constants.
(x - 4x + 6x) + (-53 + 8) + (-w)
3x - 45 - w
The terms are, 3x, -45, -w
Answer is 3x-w-45 how did I get the answer.
1. steps: x- 53 - 4x - w + 6x + 8
2. Steps: Group like terms x - 4x + 6x - w -53 + 8
3. Steps: Addsimilar elements: x - 4x + 6x = 3x
= 3x - w - 53 + 8
4. Steps: Add/Subtract the numbers: - 53 + 8 = -45
= 3x - w -45
That is your answer for this problem.

Why does the expression i to the power 4n+2 is always equal to -1
Answer:
See Below.
Step-by-step explanation:
We are given:
[tex]i^{4n+2}[/tex]
Using exponent properties:
[tex]=i^{4n}\cdot i^2[/tex]
Rewriting:
[tex]=(i^4)^n\cdot i^2[/tex]
Since i⁴ = 1 and i² = -1:
[tex]=(1)^n\cdot -1[/tex]
1 to any power is still 1:

A recipe for making 3 dozen muffins requires 1 1/2 cups of flour. How many cups of flour are required to make 5 dozen of the same muffin?
Answer:
2 1/2 cups
Step-by-step explanation:
3 dozen muffins = 1 1/2 cups
divided by 3, you get 1 dozen muffins = 1/2 cup of flour
multiply by 5 you get 2 1/2 cups of flour
At a party, the amount of people who ate meatballs was 9 less than 3/5 of the total number of people. The number of people who ate meatballs was 24. How many people where at the party? Write an equation to help you solve the problem. Let x represent the number of people at the party.
Answer:
there were a total of 55 people at the party.
Step-by-step explanation:
In order to create the equation representing this scenario we first need to represent each step in a formula. Since the total number of people is represented by x we can multiply 3/5 by x and subtract 9 from that. This would then be equal to 24 like so...
3/5x - 9 = 24
Now that we have the formula we can perform opposite operations to isolate x and solve for it.
3/5x - 9 = 24 ... add 9 on both sides
3/5x = 33 ... divide both sides by 3/5
x = 55
Finally, we can see that there were a total of 55 people at the party.
If Laura bikes x miles to and from her friend's house each day, what expression can be used to calculate the total distance she travels in a week?
x / 7
x + 7
7x
7 – x
Answer:
7x
Step-by-step explanation:
This is because x represents how many miles she rides each day, so you need to multiply x by the 7 days in a week
Harvey is studying the polynomial f(x) = (2x - 3)(x - 4)(x2 + 3) and determines that the polynomial has four real roots. Is
Harvey's statement CORRECT?
A. No, the polynomial f(x) has 2 real roots and 2 complex roots when solved.
O B. Yes, the polynomial f(x) has 4 x-intercepts so the function has 4 real roots.
C. Yes, the polynomial f(x) has a degree of 4 so the function has 4 real roots.
OD. No, the polynomial f(x) has 3 real roots because there are 3 factors.
Answer:
It is A, I highly suggest you should read my explanation.
Step-by-step explanation:
(2x - 3)(x - 4)(x^2 + 3)
Exponent of 2x = 1
Exponent of x = 1
Exponent of x^2 = 2
Add them all together to get the degree. 1 + 1 + 2 = 4
Now we can tell that the polynomial can have 1,2,3,4, or no roots at all. The max number roots it can have is 4
To see the number of roots it has, we have to set each part equal to 0
2x - 3 = 0
Add 3 to both sides
2x - 3 + 3 = 0 + 3
2x = 3
Divide both sides by 2
2x/2 = 3/2
x = 3/2 or 1.5
Next,
x - 4 = 0
Add four to both sides
x - 4 + 4 = 0 + 4
x = 4
Then,
x^2 + 3 = 0
Subtract 3 from both sides
x^2 + 3 - 3 = 0 - 3
x^2 = -3
Find the square root of both sides
sqrt(x^2) = sqrt(-3)
x = i*sqrt(3), -i*sqrt(3)
Those are imaginary numbers, therefore there are not real.
The real roots are x = 3/2, 4
Harvey stated that this equation has four real roots. We can cross options B and C out since they stated he was correct.
It is not D because finding a square root of a number gives two answers; the positive and negative version, so it will have two solutions. There were only two real roots and the other two roots are complex roots.
That leaves us to option A, which states that there are 2 real and 2 complex roots. It is correct

Caroline uses 9.1 pints of blue paint and white paint to paint her bedroom walls. 1 4 of this amount is blue paint, and the rest is white paint. How many pints of white paint did she use to paint her bedroom walls?
Answer:
6.83 pints
Step-by-step explanation:
The first step is to calculate the volume of the blue paint
= 9.1 × 1/4
= 2.275
Therefore the volume of the white paint can be calculated as follows
= 9.1 - 2.275
= 6.83
Hence the volume of white paint that Caroline used to paint her bedroom walls is 6.83 pints

first side is 3 units
3+4=7
second side is 7 units
3*3=9
third side is 9 units
how to simplify algebraic fractions
Answer:
You typically apply the same rules as you would for 'regular' fractions.
So you can multiply numerator and denominator by the same value if needed. If you want to add fractions you must make sure the denominators are the same, etc.
The value you multiply by can be an algebraic expression.
