factorize : 8a³-b³
Answers
Step-by-step explanation:
8a^3 - b^3
= (2a)^3 - b^3
= (2a -b) (4a^2 + 2ab + b^2)
An expression is defined as a set of numbers, variables, and mathematical operations. The given expression 8a³-b³ can be rewritten in factor form as (2a-b)(4a²+2ab+b²).
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
The given expression can be rewritten as,
8a³ - b³
= (2a)³ - b³
It is known that x³-y³ can also be written as (x-y)(x²+xy+y²). Therefore, the above expression can be written as,
= (2a)³ - b³
= (2a - b)[(2a)² + (2a × b) + b²]
= (2a - b)(4a² + 2ab + b²)
Hence, the given expression 8a³-b³ can be rewritten in factor form as (2a-b)(4a²+2ab+b²).

How many chirps can you expect a cricket to make in 1 min when the outside temperature is 50 ° F ? ( it’s not 75)
Answers
F = n/4 + 37, for F = 50
50 = n/4 + 37
Subtract 37 from both sides
13 = n/4
Multiply both sides by 4
52 = n
Car A is moving twice as fast as car B. Car B starts 174. Meters in front of car A. If car A passes car B in 27 seconds, how fast is car B going.
Answers
Answer: The speed of car B is 6.44 m/s
Step-by-step explanation:
Let's define:
Sa = Speed of car A.
Sb = Speed of car B.
I assume that at t = 0s, the position of car A is 0m (then at t = 0s, the position of car B is 174m)
Then we can write the positions of each car as:
Pa(t) = Sa*t
Pb(t) = Sb*t + 174m.
We also know that Sa = 2*Sb.
And we know that at t= 27s, car A passes car B.
Then at t = 27s, the positions of both cars must be the same:
Pa(27s) = Pb(27s)
Sa*27s = Sb*27s + 174m.
Now we can replace Sa by 2*Sb (from the above equation)
2*Sb*27s = Sb*27s + 174m
Now we can solve this for Sb.
2*Sb*27s - Sb*27s = 174m
Sb*27s = 174m
Sb = 174m/27s = 6.44m/s.
The speed of car B is 6.44 m/s

Step-by-step explanation:
You can break down 36 through ways down to its prime factors through multiple ways like a facor tree
36

2 2 3 3
Since two and three cannot be broken down anymore, they are prime factors. Also, because you are left with two 2s and two 3s, you would mark that as squared when giving an answer.

For a certain city, the temperature each day this week can be described by the inequality below.

In the inequality, d is the daily temperature in degrees Fahrenheit and A is the average temperature for the year. If A = 54 °F, which statement BEST interprets the solution to the in
A The temperature each day this week was less than 90 "F
B The average temperature for the year was less than 90 °F
c The temperature each day this week was less than 72 °F
DO The average temperature for the year was less than 72 °F
Answers
Answer:
Option C.
Step-by-step explanation:
We have the following inequality :
[tex]3d+6<A[/tex] (I)
In which :
[tex]d[/tex] : '' The daily temperature in degrees Fahrenheit ''
[tex]A[/tex] : '' The average temperature for the year ''
We first need to find the solution (the inequality related to the value of [tex]d[/tex]) given that we set [tex]A=54[/tex] °F ⇒
Using the equation (I) :
[tex]3d+6<54\\3d<48\\d<16[/tex]
We find that the ''[tex]d[/tex]'' variable (daily temperature in degrees Fahrenheit) is less than [tex]16[/tex] °F.
The option B and the option D give us an interpretation about the [tex]''A''[/tex] variable.
Only the options A and C give us an interpretion about the [tex]''d''[/tex] variable
Between A and C, the option C is a more accurate option (because 72°F is closer to 16°F).
We answer that the option C best interprets the solution.
Both of the equations below have the same solution when solved for x. What is the value of t?
Answers
Answer:
-.75x-6
Step-by-step explanation:
Step 1: simplify the first equation
1/4(x-28)=2x, or .25x-7=2x.
Step 2: simplify the second equation so that one side equals 2x
13-5x=-7.5x-t. Add 7x to either side to get 13+2x=-.5x-t. Then, subtract 13 from either side and then you have 2x=-.5x-t-13
Step 3: make both equations into one equation
Since 2x=.25x-7, and 2x=-.5x-t-13, then it's safe to say .25x-7=-.5x-t-13.
Step 4: Simplify this final equation
Add .5x to both sides to get .75x-7=-t-13. Then add 13 to both sides to get .75x+6=-t. Then multiply everything by -1 to get -.75x-6=t

Find the extraneous solution of the equation |4x−42|=−10x.
Answers
Answer:
x=3 is the extraneous solution
Step-by-step explanation:
|4x-42| = -10x
Since it's absolute value and we know that there are two possibilities, we need two equations to set up to solve for x.
1st equation:
4x - 42 = -10x2nd equation:
4x - 42 = 10xSolve both equations for x:
1st equation:4x - 42 = -10x14x-42 = 014x=42x = 32nd equation:4x-42=10x-6x-42=0-6x=42x=-7Plug in both values for x in the original equation to find the extraneous solution:
x=-7
|4x-42|=-10x|4(-7)-42|=-10(-7)|-28-42|=70|-70|=7070=70x=3
