Which Expression Can Be Used To Determine the nth term in the pattern below<br> 20,25,30,35,40
maw [93]

Answer:

see explanation

Step-by-step explanation:

These are the terms of an arithmetic sequence with n th term

a_{n} = a + (n - 1)d

where a is the first term and d the common difference

d = 25 - 20 = 30 - 25 = 5 and a = 20, hence

a_{n} = 20 + 5(n - 1) = 20 + 5n - 5 = 5n + 15 ← n th term formula

Use the Distributive Property to write each expression as an equivalent algebraic expression.
Romashka [77]

Answer:

9x - 45

Step-by-step explanation:

To simplify this expression, we need to use Distributive Property to get rid of the parentheses. So, we multiply the -9 by everything inside the parentheses.

-9(-x + 5)

-9 · -x = 9x

-9 · 5 = -45

Now we add our products together.

9x + -45

Since there is a '+' sign and a '-' sign next to each other, we can simplify it to just a '-'.

9x - 45

Hope this helped! Let me know if you have any other questions! :)

lozanna [386]
The volume of a cylinder is given by πr²h
r= x-3, while h =2x+7
Thus; volume = π(x-3)²(2x+7)
                       =π(x²-6x+9)(2x+7)
                       =π( 2x³-12x²+18x +7x²-42x+63
                       = π(2x³-5x²+24x+63) cubic units
