4n^(2)+4n=3 Please help with the work

Mathematics
1 answer:
Kaylis [27]2 years ago
3 0

Answer:

n= 1/2 ( \frac{1}{2} )  or  (0.5)

AND

n= -3/2 ( -\frac{3}{2} ) or (-1.5)

Step-by-step explanation:

4n^2+4n=3

step1: move 3 to the other side and make the equation equal to zero.

4n^2+4n-3=0

step2: factorise the equation.

(2n-1)(2n+3)=0

step3: make each bracket equal to zero.

2n-1=0

2n+3=0

step4: solve for n values.

<u>1.</u> 2n-1=0

(add 1 for both sides)

2n=1

(divide by 2 for both sides)

n= 1/2 ( \frac{1}{2} )  or  (0.5)

<u>2.</u> 2n+3=0

( subtract 3 for both sides)

2n=-3

(divide by 2 for both sides)

n= -3/2 ( -\frac{3}{2} ) or (-1.5)

How should this model be completed to represent 642/11 ??<br><br> Enter the answer in the box.
Rashid [163]

Model be completed to represent 642/11 is 29.1818181818

\frac{642}{11} = 58.3636363636

58.3636363636 = 583.636363636 to the nearest tenth

58.3636363636 = 58.36 to the nearest hundredth

58.3636363636 = 58.364 to the nearest thousandth

= 0 to the nearest tenth

= 0 to the nearest hundredth

= 0 to the nearest thousandth

642 divide by half plus 20

(\frac{642}{2}) + 20 = 341

642 divide by half plus 40

(\frac{642}{2}) + 40 = 361

\frac{642}{11} divided by 2

(\frac{642}{11}) ÷ 2 = 29.1818181818

Division is  one among  the four basic operations of arithmetic, the  ways in which  numbers are combined to make new numbers.  the opposite  operations are addition, subtraction, and multiplication.

At an elementary level the division of two natural numbers is, among other possible interpretations,  the method  of calculating the number of times one number is contained within another.7  This number of times  needn't  be an integer.  for instance , if 20 apples are divided evenly between 4 people, everyone receives 5 apples (see picture).

The division with remainder or Euclidean division of two natural numbers provides an integer quotient, which  is that the  number of times the second number is completely contained in the first number, and a remainder, which  is that the  part of the first number that remains, when  within the  course of computing the quotient, no further full chunk of  the dimensions  of the second number can be allocated.  for instance , if 21 apples are divided between 4 people, everyone receives 5 apples again, and 1 apple remains.

For division to always yield one number  instead of  a quotient plus a remainder, the natural numbers must be extended to rational numbers or real numbers.

Eric is planning to paint the four pillars that are attached to the front of his house. But, he needs to know how many square fe
mariarad [96]
Assume that the pillars are cylindrical..you're looking for the lateral surface area correct? to get the lateral surface area, you use the formula LSA = 2rh(pi) where r is radius h is height substitute the values... h = 10 d = 1 so r =1/2 so LSA = 2 (1/2)(10)(3.14) LSA = 10(3.14) LSA = 31.4 sq ft :D                                      Can You Mark Me Brainlest Plz...

A cylindrical grain bin has a radius of 7 feet and a height of 25 feet. How many cubic feet can the unit hold?
Alex17521 [72]

Answer:

3847 ft³

Step-by-step explanation:

The volume of a cylinder of radius r and height h is V = πr²h.

Here, the volume is V = π(7 ft)²(25 ft) = 1225π ft³, or approximately 3847 ft³.
