Answer:
Given : Expression -
To find : How would the sum of cubes formula be used to factor given expression? Explain the process. Do not write the factorization.
Solution :
The formula of sum of cubes is,
First we convert the given expression in
Apply exponent rule :
Rewrite
Therefore, could be written as
On comparison with the formula,
a=xy , b=7
Answer:
i can read it
Step-by-step explanation:
Answer:
Given,
The total distance covered = 4 km,
Since, initially he would be in rest,
So, his starting point would be 0.
Now, his first break = km,
Second break = km,
Also, we can write,
Drawing number line:
Step 1: Draw a line.
Step 2: Make 12 marks in same distance.
Step 3: Starts from 0, then 1/3, 2/3, 3/3 and so on.
Thus, we can show Wayne's bike on a number line as below.
-3 - (-10) - 8
The double negative sign changes the sign to a positive sign.
-3 + 10 - 8
Solve -3 + 10 first.
-3 + 10 = 7
Now solve 7 - 8.
7 - 8 = -1
-1 is your answer.
Answer: x-9
Step-by-step explanation: You can rewrite that to get 4/3x-1/3x-5-4
That simplifies to x-9
