Answer:
21d(10d-3)
Step-by-step explanation:
21d x 10d = 210d^2
21d x 3 = -63d
so it would be 210d^2 - 63d
Answer:
Step-by-step explanation:
1. To solve this problem you must apply the formula for calculate the area of a square, which is:
Where s is the lenght of a side of the square.
2. By definition, the sides of the square have equal lenghts. You can calculate the lenght of a side by calculating the distance between two vertices of the aquare:
Where is the lenght of the side AB.
3. The area is:
The pattern in this is
, where n is the previous number in the sequence and x is the number you multiplied a number by to get the previous number. You start with twelve times two, then increase the number you multiply by by one.
The next number in the sequence is
1440.
Answer:
Step-by-step explanation:
Let's rewrite 1 as 1 ^3.
Now, we can apply the "Difference of Cubes Formula".
