Answers
Answer:
In bold.
Step-by-step explanation:
a. (x+5)^2 – 3x(x+5) x+5 is common
= (x + 5)(x + 5 - 3x)
= (x + 5)(5 - 2x)
b. (x + 5)(5 - 2x) = 0
x = -5, 2.5.
2a. Area of the square = (x + 5)^2
Area of triangle AEB
= 1/2 * base * height
I am assuming that H is the centre of AB , so
Area = x*x
= x^2.
2b
6x^2 = (x + 5)^2
6x^2 = x^2 + 10x + 25
5x^2 - 10x - 25 = 0
x^2 - 2x - 5 = 0
x = [-(-2) +/- sqrt(2^2 - 4*1*-5)] / 2
x = -1.45, 3.45.
(we ignore the negative).

what Should be added To -6(-p-1) to get 3p³+5p²+6p-2?
Answers
Answer:
3p³ + 5p² - 8
Step-by-step explanation:
Given:
6p - 2
-6(-p-1) = 6p + 6
Subtract 6p + 6 from 3p³ + 5p² + 6p - 2 get your answer
= 3p³ + 5p² + 6p - 2 - (6p + 6)
= 3p³ + 5p² + 6p - 2 - 6p - 6
= 3p³ + 5p² - 8
3p³ + 5p² - 8 Should be added To -6(-p-1) to get 3p³+5p²+6p-2

Hey there! If you have any questions feel free to let me know in the comments below.
Step 1: Subtract 36 from both sides.
3x = 96 - 36
Step 2: Simplify 96 - 36 to 60.
3x = 60
Step 3: Divide both sides by 3.
x = 60/3
Step 4: Simplify 60/3 to 20.
x = 20

A pack of pencils contain a dozen pencils.450 such packs were put in a carton. If there are 25 such cartons, find the total number of pencils.
Answers
Answer:
135000
Step-by-step explanation:
Given: A pack of pencils contain a dozen pencils. 450 such packs were put in a carton. There are 25 such cartons.
To find: total number of pencils
Solution:
Total number of pencils in a pack = 1 dozen = 12
Total number of packs = 450
Total number of cartons = 25
Total number of pencils = 12 × 450 × 25 = 135000
So, total number of pencils is 135000.

A piece of land is 8 1/2 miles wide. It is 4 7/8 times as long as it is wide. How long is the piece of land.
Answers
Answer:
[tex]Length = 41\frac{7}{16}[/tex]
Step-by-step explanation:
Given
[tex]Width = 8\frac{1}{2}[/tex]
[tex]Length = 4\frac{7}{8}[/tex] times as long as the width
Required
Determine the length
To do this, we simply multiply the length by [tex]4\frac{7}{8}[/tex]
So, we have:
[tex]Length = 4\frac{7}{8} * Width[/tex]
Substitute [tex]8\frac{1}{2}[/tex] for width
[tex]Length = 4\frac{7}{8} * 8\frac{1}{2}[/tex]
Convert to improper numbers
[tex]Length = \frac{39}{8} * \frac{17}{2}[/tex]
[tex]Length = \frac{39*17}{8*2}[/tex]
[tex]Length = \frac{663}{16}[/tex]
[tex]Length = 41\frac{7}{16}[/tex]

Answer:
A. -1, multiplicity 1; 0, multiplicity 1; 3, multiplicity 1.
Step-by-step explanation:
Let [tex]f(x) = -x^{3}+2\cdot x^{2} + 3\cdot x[/tex], to determine its roots and multiplicities we proceed to factorize the polynomial:
1) [tex]-x^{3}+2\cdot x^{2} +3\cdot x[/tex] Given

60 milligrams = ______ km
Answers
The value of 60 milligrams after unit conversion is 0.00006 Kg.
What is Unit Conversion?A unit conversion expresses the same property as a different unit of dimension. For case, time can be expressed in twinkles rather of hours, while distance can be converted from long hauls to kilometers, or bases, or any other measure of length.
A conversion factor is an expression for the relationship between units that's used to change the units of a measured volume without changing the value.
We have to convert 60 mg to Kg.
As, 1 Kg = 1000 g
and, 1 gm = 1000 mg
So, 1 mg = 1/ 1, 000, 000 Kg
Then, the conversion is
= 60 / 1, 000, 000
= 6/ 100,000
= 0.00006 Kg

Step-by-step explanation:
First we will solve the expression:

Solving:
First we will take negative sign common, then take LCM of denominator and simplify the expression.
[tex]=\frac{3x}{2x-6}+\frac{9}{\textbf{-}(2x-6)}\\=\frac{3x}{2x-6}+\frac{\textbf{-}9}{(2x-6)}\\Taking\:LCM\\=\frac{3x-\mathbf{9}}{2x-6}\\=\frac{\mathbf{3}(x-\mathbf{3})}{\mathbf{2}(x-3)}\\=\mathbf{\frac{3}{2}}[/tex]
