Part A: One of the factors of the polynomial function p(x)=2x^4+3x^3−x is (2x−1).
Write p as the product of (2x−1) and another polynomial.
Part B: What are the solutions to the equation p(x)=0? Enter the solutions from least to greatest.
Answer:
Step-by-step explanation: 2x+6
Another factor will be x and ( x + 1 )² and the solution will be -1, 0, and 1/2.
What is expansion?In mathematics, every real-world issue may be transformed into an equation, sometimes in the form of a factor, which must then be expanded to get a solution.
Expanded form is the term used in mathematics to refer to the process of expanding a number to convey the value of every digit and place value.
Given,
p(x)=2x⁴ + 3x³ −x one factor is (2x−1)
To find another factor we divide p(x)=2x⁴ + 3x³ −x by (2x−1)
Then we got remainder as 0 and quotient ( x³ + 2x + 1 )
So,
(2x−1) ( x³ + 2x² + x ) = 0
(2x−1) (x) ( x² + 2x + 1) = 0
(2x−1) (x) (x + 1)² = 0
Now the solution to this
(2x−1) = 0 ⇒ x = 1/2
(2x−1) (x) ( x² + 2x + 1) = 0 ⇒ x = 0
And
(x + 1)² = 0 ⇒ x = -1
Hence, another factor will be x and ( x + 1 )² and the solution will be -1, 0, and 1/2.

The length of a rectangular plot of land is 2m more than its breadth. If it's area is 120m^2, find its length and breadth.
Answer:
length is 40 and breadth is 20
Step-by-step explanation:
120 =2( l + b )
120 = 2( 2x +x )
120= 2 x 3x
120 =6x
120/6 = x
20 = x
length=2x = 2 x 20 = 40
breadth= x = 20.

135
Step-by-step explanation:
what was the difficulty here ?
supplementary angles fill up to 180°.
complementary angles fill up to 90.
50° complement is 90-50 = 40°.
supplement is 180-50 = 130°.
bisected angle is 50/2 = 25°.
90-34=56° complement is 34°.
supplement is 180-56 = 124°.
bisected angle is 56/2 = 28°.
35×2=70° complement is 90-70 = 20°.
supplement is 180-70 = 110°.
bisected angle is 35°.
180-135=45° complement is 90-45 = 45°.
supplement is 135°.
bisected angle is 45/2 = 22.5° = 22°30'
if n^3=x and n^4=20x , where n>0, what is the value of x?
Step-by-step explanation:
∠2 and ∠7 are alternate exterior angles so they are equal.
So you can create the equation
40x-48 = 20x+52 Subtract 20x from both sides. Add 48 to both sides.
20x = 100
x = 5
if you need m∠2 Substtute 5 for x in 20x+52
20(5) + 52 = 100 +52 m∠2= 152°
m∠7 40(5) - 48 = 200-48 m∠7= 152°
The value of the variable x is given as 8000.
What are the rules of exponents?Some of the rules of exponents are as follows,
The product of two exponents having the same power is equal to the power of their base multiplied.
The product of two exponents having the same base is equal to the sum of the powers of different exponents to the same base.
The given exponential expressions are as below,
n⁴ = 20x
And, n³ = x
Then as per the rule of exponent, the following it can be written as,
n³ = x
⇒ n × n³ = n × x
⇒ n⁴ = nx
⇒ 20x = nx
⇒ n = 20
Then, x = 20³ = 8000
Hence, the value of x is found to be 8000.

An artist makes necklaces. She packs each necklace in a small jewelry box that is134inches by 214 inches by 34 inch. A department store ordered 270 necklaces. The artist plans to ship the necklaces to the department store using flat-rate shipping boxes from the post office. Which of the flat-rate boxes should she use to minimize her shipping cost?
Answer:
Small flat rate box
Step-by-step explanation:
Since she sells necklaces we can assume that the question is missing spaces and the actual dimensions are 1 3/4inch by 2 1/4 inch by 3/4 inch. This being the case she can use the Small flat rate box from the local post office for her necklaces. This is the smallest flat rate packaging available aside from envelopes, but since the artist needs a 3dimensional box the envelopes would not work. This small flat rate box has the following dimensions 8 11⁄16″ x 5 7⁄16″ x 1 3⁄4″ it also can hold up to 70lbs which far exceeds the weight of the necklaces.

Gina deposits $150 at the start of each year into a college savings account that pays 2% simple interest at the end of each year. She does not deposit the interest she earn each year. How much total interest will Gina Earn on her deposit through the end of the fifth year?
Answer:
$45
Step-by-step explanation:
Given the following :
Amount deposited in first year = $150
Interest rate (r) = 2% = 0.02
First year:
Simple Interest = principal * rate * time
= $150 * 0.02 = $3
2nd year:
Principal = $150 * 2 = $300
($300 * 0.02) = $6
3rd year:
Principal = $150 * 3 = $450
($450 * 0.02) = $9
4th year:
Principal = $150 * 4 = $600
(600 * 0.02) = $12
5th year:
Principal = $150 * 5 = $750
($750 * 0.02) = $15
Total interest earned :
$(3 + 6 + 9 + 12 + 15)
= $45

A group of friends were working on a student film that had a budget of $800. They spent all their budget on props and equipment. They used 83% of their budget on equipment. How much money did they spend on props?
Answer:
$136
Step-by-step explanation:
100% - 83% = 17%
the 17% is on props.
so, take 17/100 and multiply with $800, which you will get 136.
so the amount of money spent on props is $136
Min wants to make 100 name tags with ribbons attached to them. Each name tag requires five centimeters of ribbon. She has 3.25 meters of ribbon. Exactly how many more centimeters of ribbon does Min still need to make 100 name tags?
A: 175
B: 305
C: 325
D: 825
Do it Step By Step
Answer:
a; 175 centimeters
Step-by-step explanation:
One meter is 100 centimeters
this means that 3.25 meters is essentially just 325 centimeters
if she wants to make 100 name tags she must do 100 times 5 to get how many centimeters of ribbons she needs
100 * 5 = 500
she only has 325 centimeters so you subtract 325 from 500
500 - 325 = 175
