Answer:
−8x^4 + 5x^3 + x^2
Step-by-step explanation:
3x^3 + x^2 + 2 (x^3 − 4x^4)
Apply the distributive property.
3x^3 + x^2 + 2x^3 + 2 (−4x^4)
Multiply −4 by 2.
3x^3 + x^2 + 2x^3 − 8x^4
Simplify by adding terms.
Add 3x^3 and 2x^3.
5x^3 + x^2 − 8x^4
Simplify the expression.
Move x2.
5x^3 − 8x^4 + x^2
Reorder 5x^3 and −8x^4.
−8x^4 + 5x^3 + x^2

Erika and Bradley want to hike the Big Cypress Trail. They will hike a total of 72 milles FErika and Bradley want to hike 16 miles each day, how many days will they hike exadty 16 miles? They will hike exactly 16 miles each day for days.
Answer: They will hike exactly 16 miles each day for 4 days.
Step-by-step explanation:
Given: Total distance to hike = 72 miles
They hike 16 miles per day.
Total days they will take to complete the distance = [tex]\dfrac{\text{Total distance to hike}}{\text{Distance hiked each day}}[/tex]
[tex]=\dfrac{72}{16}\\\\=\dfrac{9\times8}{2\times8}=\dfrac92\\\\=4\dfrac12[/tex]
It will take 4 complete days and a half day to complete the journey.
i.e. They will hike exactly 16 miles each day for 4 days.

Maria deposited $5,700 in an account that earns 8% simple interest. Maria made no withdrawals or deposits. What will be the total amount of money in her account after 6 years?
Answer:
The total amount of money in Maria's account after 6 years is $8436
Step-by-step explanation:
Given;
principal amount , P = $5,700
interest rate, r = 8 % = 0.08
time of investment, t = 6 years
The interest on the invested money after 6 years is given by;
I = Prt
I = $5,700 x 0.08 x 6
I = $2736
Total amount in Maria's account is given by;
A = P + I
A = $5,700 + $2736
A = $8436
Therefore, the total amount of money in Maria's account after 6 years is $8436

Amino acids are used to build _______?
Answer:
Polypeptides
Step-by-step explanation:
A sequence of amino acids are joined together by peptide bonds to form a polypeptode chain;
This chain then folds and twists (via intramolecular forces/attractions) into a 2D or 3D shape and may even join with another polypeptide chain to form a protein.
Give an ordered pair on the graph and explain it’s meaning in the real world context.
Step-by-step explanation:
See my attached graph for what this problem looks like. I used the equation y=5x because each bargain DVD (x) is $5 and equals the total cost (y).
One ordered pair would be (1,5). This means that 1 bargain DVD costs $5.

In the diagram how are angles AED and DEC related? choose all that apply
Options: They are vertical angles
They are supplementary angles
They are adjacent angles
They are right angles
Answer:
they are supplementary
Step-by-step explanation:
The angles AED and DEC are adjacent angles option (C) They are adjacent angles is correct.
What is an angle?When two lines or rays converge at the same point, the measurement between them is called an "Angle."
It is given that:
The diagram is shown in the picture.
As we can see in the diagram,
The angle AED and DEC are sharing a common vertex which means they are adjacent angles.
Thus, the angles AED and DEC are adjacent angles option (C) They are adjacent angles is correct.

Molly invested $50,000 in various stocks and bonds. She earned 15% on the bonds and 18% on the stocks. Molly's total profit on both types of investments was $8700, how much of the $50,000 did she invest in bonds?
Answer:
$10000
Step-by-step explanation:
Given that:
Molly invested $50,000 in various stocks and bonds.
She earned 15% on bonds and 18% on stocks
Let the bonds be denoted by a
However, her profit on both types of investment is said to be $8700
We are to find how much of the $50,000 did she invest in bonds.
i.e
0.15a + 0.18(50000-a) = 8700
open brackets
0.15a + 9000 - 0.18a = 8700
Collect like terms
0.15a - 0.18a = 8700 - 9000
-0.03a = -300
Divide both sides by(-0.03); we get
a = 10000
Thus, Molly invested $10000 in the bonds.

A hyena can run one over four of a mile in 22.5 seconds. At this rate, which equation can be used to determine how fast a hyena runs in miles per hour? (5 points)
one-fourth mile over twenty-two point five seconds = 40 miles per hour
twenty-two point five seconds over one-fourth mile = 40 miles per hour
one-fourth mile over twenty-two point five seconds = 90 miles per hour
twenty-two point five seconds over one-fourth mile = 90 miles per hour
200 miles in total?
