4(3-2t)
factor x^3+25 completely
Answer:
Please check the explanation.
Step-by-step explanation:
Given the expression
[tex]\:x^3+25\:[/tex]
Please note that the given expression could not factor further.
But, wait!
Let me take a sample expression and factor that sample expression so that you could get an idea of how to factorize the expression
Given the sample expression
[tex]x^2-5x+6[/tex]
Breaking the expression into groups
[tex]\:x^2-5x+6=\left(x^2-2x\right)+\left(-3x+6\right)[/tex]
Factor out x from x²-2x: x(x-2)
Factor out -3 from -3x+6: -3(x-2)
[tex]=x\left(x-2\right)-3\left(x-2\right)[/tex]
Factor out the common term (x-2)
[tex]=\left(x-2\right)\left(x-3\right)[/tex]
Thus, factorizing the expression such as:
[tex]x^2-5x+6=\left(x-2\right)\left(x-3\right)[/tex]

On being asked her age, Shalu replies, 'My brother was born 2 years before me and my sister 4 years after me, and the sum of their ages is 30 years." How old is Shalu?
Shalu is 16 years old.
The equation can be defined as a mathematical term that refers to a situation in which several factors must be considered. It is defined as the state of being equal and is frequently represented as a math expression with equal numbers on either side.
Two expressions joined by an equal sign form a mathematical statement known as an equation.
Shalu's brother was born 2 years before Shalu.
Shalu's sister was born 4 years after Shalu.
And the sum of Shalu's brother and sister's age is 30 years.
Let x be the age of Shalu.
As Shalu's brother was born 2 years before her = x + 2
As Shalu's sister was born 4 years after her = x - 4.
Therefore,
x + 2 + x - 4 = 30
2x - 2 = 30
Adding 2 on each side of the equation,
2x -2 + 2 = 30 + 2
2x = 32
Dividing each side of the equation by 2.
2x / 2 = 32 / 2
x = 16
Therefore, Shalu is 16 years old.

..............
Answer:
C
Step-by-step explanation:
4 ounce costs $1.79
12 ounce costs $4.11
$1.79 ÷ 4 = 0.4475 per ounce
$4.11 ÷ 12 = 0.3425 per ounce
0.3425 < 0.4475
So the 12 ounce tube is the better buy becaus it is cheaper per ounce.

G is the centroid of AABC, FC = 35, AG = 42, BF = 57, and DG = 14. Find BG.
Answer:
[tex] BG = 38 [/tex]
Step-by-step explanation:
Based on centroid theorem of triangles:
[tex] BG = \frac{2}{3} \times BF [/tex]
[tex] BF = 57 [/tex]
Plug in the value into the equation
[tex] BG = \frac{2}{3} \times 57 [/tex]

DC is given as 46
Remark
Triangle CED is similar to AEB by SAS for similarity
Therefore DC is 1/2 the size of AB
Solution
1/2 AB = DC
1/2 AB = 46 Multiply both sides by 2
AB = 2*46
AB = 92

Which equation calculates the number of 1/8 foot pieces you can cut from 5 feet of ribbon
Answer:
40
Step-by-step explanation:
The number ribbons cut from the 5 feet long one is 40 ribbons, the equation is n = 5÷1/8
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
For example, 3x - 5 = 16 is an equation.
Given that, a ribbon of 5 feet long ribbon is cut into n 1/8-foot-long ribbons, we need to determine the equation calculates the number of 1/8 foot pieces,
So, the equation =
n = 5÷1/8
n = 40
Hence the number ribbons cut from the 5 feet long one is 40 ribbons, the equation is n = 5÷1/8
