Sequence will look like this:
Term 1: 20 --------- 20 + 5(0)
Term 2: 25 --------- 20 + 5(1)
Term 3: 30 --------- 20 + 5(2)
Term 4: 35 --------- 25 + 5(3)
ETC.
It cab noted that the numbers in the bracket (that is, 0, 1, 2, 3, 3, etc) = n-1
Then, the explicit formula will be;
an = 20 + 5(n-1).
The correct answer is D.
<span>224 7/10 is a mixed fraction ..so first we convert it into an improper fraction ...
=> for that follow these steps ...
=> 224 X 10 + 7
=> 2247/10

Answer:
+ 3x³ - 3x - 1
Step-by-step explanation:
The area (A) of a rectangle is calculated as
A = lw ( l is the length and w the width ) , thus
A = (3x² - 2x - 1)(x² + x + 1)
Each term in the second factor is multiplied by each term in the first factor, then
A = 3x²(x² + x + 1) - 2x(x² + x + 1) - 1(x² + x + 1) ← distribute parenthesis
= 3 + 3x³ + 3x² - 2 - 2x² - 2x - x² - x - 1 ← collect like terms
= + 3x³ - 3x - 1
Answer:
Step-by-step explanation:
Given
--- scale factor
Required
Relationship between ABC and A"B"C"
implies that the sides of A"B"C" are bigger than ABC
i.e.
In
Divide both sides by A"B"
Divide both sides by 2
Rewrite as:
(a) is correct
