Using the Associative Property of addition, if you move the parentheses anywhere between a, b, and c, the answer will always be the same. Also, the Commutative Property of addition states that if you move the terms around, the answer is also still the same. So, (a+b)+c is the same as b+(a+c).

Algebraic Expression: The length of a rectangle is five inches less than triple the width. If the width is w inches, how long is

Montano1993 [528]

Answer:

l=(3w-5) Inches

Step-by-step explanation:

Let the width of the rectangle =w inches

The length of a rectangle is five inches less than triple the width.

Let us break the statement down into parts.

Triple the width=3w
Five inches less than triple the width =3w-5

Therefore, the length of the rectangle, l= <u>(3w-5) Inches</u>

Answer: $\bold{a_1=6,\quad a_n=-3a_{n-1}}$

<u>Step-by-step explanation:</u>

The recursive rule for a general geometric sequence is: $a_n=a_{n-1}(r)\quad \text{where}\ a_{n-1}\ \text{is the previous term and r is the ratio}$

Given the sequence {6. -18, 54, -162, ... }, we can see that

$\text{the first term}\ (a_1)\ \text{is 6}$
$\text{the common ratio (r) is:}\ \dfrac{-18}{6}=-3$

So, the recursive rule is: $a_n=-3a_{n-1}$
