Answer:

3v^2\left(5v^6-7v^3\right)=15v^8-21v^5

Step-by-step explanation:

Given the expression

3v^2\left(5v^6-7v^3\right)

Apply the distributive law

a\left(b-c\right)=ab-ac

a=3v^2,\:b=5v^6,\:c=7v^3

=3v^2\cdot \:5v^6-3v^2\cdot \:7v^3

=3\cdot \:5v^6v^2-3\cdot \:7v^3v^2

=15v^8-21v^5

Thus, we conclude that

3v^2\left(5v^6-7v^3\right)=15v^8-21v^5

Write the first 4 terms in the sequence defined by the explicit rule f(n)=n^2 - 5 *n^2 means n squared
Deffense [45]
The question did not spesify the stating value for n.

Assuming, n = 0 is the starting value.

1st term is when n = 0:
f(0) = (0)^2 - 5 = 0 - 5 = -5

2nd term: f(1) = (1)^2 - 5 = 1 - 5 = -4

3rd term: f(2) = (2)^2 - 5 = 4 - 5 = -1

4th term: f(3) = (3)^2 - 5 = 9 - 5 = 4

Therefore, the first 4 terms are: -5, -4, -1, 4.

Tell whether the given value is a solution of the inequality.<br> x + 1 &gt; 10; x = 9
Oliga [24]

Answer:

given x+1 > 10,

x > 10 - 1

x > 9

which means x MUST BE more than 9 , which also means 9 isnt included in the inequality therefore x = 9 is not a solution.
