expeople1 [14]

Answer:

7 ( 3x + 5y) = <u>21x+35y</u>

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

<u>Step 1 : </u> apply the distributive law. <u>("the law relating the operations of multiplication and addition")</u>

<em>a ( b + c ) = ab + ac</em>

7 ( 3x + 5y) = 7 x 3x + 7 x 5y

<u>Step 2 : simplify  </u>7 x 3x + 7 x 5y

So, the answer is <u>21x+35y</u>

Describe the relationship between the terms in each arithmetic sequence. Then
shtirl [24]

Answer:

(a) The sum of the previous term and 9

(b) 36, 45, 54

Step-by-step explanation:

Given

Sequence: Arithmetic Progression

0,9,18,27

Solving (a): Describe the relationship in each term

First, we calculate the common difference (d)

In arithmetic progression:

d = T_n - T_{n-1}

Take n as 2

d = T_2 - T_{2-1}

d = T_2 - T_{1}

Where

T_2 = 9\ and\ T_1 = 0

d =9-0

d =9

<em>The relationship is: The sum of the previous term and 9</em>

Solving (b): The next three terms

As said in (a) each term is derived from a sum of 9 and the previous term

So, we have:

Next\ Term = 27 + 9 = 36

Next = 36 + 9 = 45

Next = 45 + 9 = 54

Hence, the next three terms are: 36, 45 and 54
