(2x5 + 7x3) – (5x2 - 4x3)
simply
Answer:
(2x4 + 11x2 - 5)
Step-by-step explanation:
((2•(x5))+(7•(x3)))-(5x-22x3)
((2 • (x5)) + 7x3) - (5x - 4x3)
(2x5 + 7x3) - (5x - 4x3)
2x5 + 11x3 - 5x = x • (2x4 + 11x2 - 5)
Factoring 2x4 + 11x2 - 5
Multiply the coefficient of the first term by the constant 2 • -5 = -10
Find two factors of -10 whose sum equals the coefficient of the middle term, which is
10 + 1 = -9
-5 + 2 = -3
-2 + 5 = 3
-1 + 10 = 9

Multiply all terms by (x-3)(x+3) and cancel:
x(x+3)+2x(x−3)=18
3x2−3x=18(Simplify both sides of the equation)
3x2−3x−18=18−18(Subtract 18 from both sides)
3x2−3x−18=0
3(x+2)(x−3)=0(Factor left side of equation)
x+2=0 or x−3=0(Set factors equal to 0)
x=−2 or x=3

The number line is shaded from the circle to negative 5. What is another way to represent this solution set? {x | x < 4. 5} {x | x ≤ 4. 5} {x | x > 4. 5} {x | x ≥ 4. 5}.
The solution set for the number line of inequality can be represented as,
{x | x ≤ 4. 5}
What is the number line?The number line is the way of representation of number and digits in a arranged form to understand the data batter.
The meaning of circle in number line,
Open circle-When the value of the variable is equal to the given number, then the graph of the inequality has an open circle.Closed circle or solid circle-When the value of variable is not equal to the given number, then the graph of the inequality has a closed circle.The number line going from negative 5 to positive 5 and a solid circle appears between positive 4 and positive 5. The middle point of 4 and 5 is 4.5.
The solid or closed circle means that the value has less than or equal to 4.5. Thus, the solution set for the number line of inequality can be represented as,
{x | x ≤ 4. 5}

what is x - 2 5/8 = 6 1/4
Answer:
x = 7 5/8
Step-by-step explanation:
Given:
x - 2 5/8 = 6 1/4
first, let's find a common denominator so we can deal with the fractions easier.
The smallest number 8 and 4 is divisible by, is 8.
so we just multiply everything in the equation by 8 now, this helps get rid of the fractions.
x - 2 5/8 = 6 1/4
8 (x -2 5/8) = 8 (6 1/4)
simplifies into
8x -16 + 5 = 48 + 2
simplify some more
8x -11 = 50
solve for x
8x = 11 + 50
8x = 61
x = 61/8
or
x = 7 5/8
Answer:
Decimal: x=8.87
Improper fraction: x=71/8
Mixed number: x=8 7/8
Step-by-step explanation:
[tex]x-2\frac{5}{8}=6\frac{1}{4}[/tex]
First, let's convert mixed numbers to improper fraction
[tex]x-\frac{21}{8}=\frac{25}{4}[/tex]
Now, we can add 21/8 to both sides
[tex]x-\frac{21}{8}+\frac{21}{8}=\frac{25}{4}+\frac{21}{8}[/tex]
[tex]x=\frac{71}{8}[/tex]
We can convert 71/8 to a mixed number
[tex]x=8\frac{7}{8}[/tex]

At what rate is the diagonal of a cube increasing if its edges are increasing at a rate of 6.4 cm/s?
Answer:
11.08 cm/s
Step-by-step explanation:
Here it is given that the edges of a cube are increasing at a rate of 6.4 cm/s . And we need to find out the rate at which the diagonals are increasing . If we assume each side of the cube to be x , then ;
[tex]\longrightarrow \dfrac{da}{dt}= 6.4 \ cm/s\dots (i) [/tex]
Now we can find diagonal as ,
[tex]\longrightarrow d = \sqrt{ length^2+breadth^2+height^2} [/tex]
Here l = b = h = a ; so ,
[tex]\longrightarrow d =\sqrt{ a^2+a^2+a^2} [/tex]
Simplify,
[tex]\longrightarrow d =\sqrt{3a^2} [/tex]
Take out a from square root,
[tex]\longrightarrow d =\sqrt3 a[/tex]
Now , we can find the rate of change of diagonal as ;
[tex]\longrightarrow r =\dfrac{d\sqrt3 a}{dt} [/tex]
Take out the constant,
[tex]\longrightarrow r = \sqrt3\dfrac{da}{dt} [/tex]
From equation (i),
[tex]\longrightarrow r = 1.732 \times 6.4 \ cm/s [/tex]
Multiply ,
[tex]\longrightarrow \underline{\underline{ rate_{of\ change \ of \ diagonals}= 11.08\ cm/s}}[/tex]
This is the required answer!
If the side length increases at a rate of 6.4 cm/s, then the diagonal increases at a rate of 11.1 cm/s
At what rate does the diagonal increase?
The diagonal of a cube of side length S is given by:
d = S*√3
In this case, we know that the side length increases at a rate of 6.4 cm/s, then we can write:
S = S₀ + 6.4cm/s*t
Where S₀ is the initial side length, replacing that on the diagonal formula we get:
d = (S₀ + 6.4cm/s*t)*√3
Now if we differentiate it with respect to the time t, we get:
d' = 6.4cm/s*√3 = 11.1 cm/s
So, if the side length increases at a rate of 6.4 cm/s, then the diagonal increases at a rate of 11.1 cm/s.
