Write a variable expression to describe the rule for the sequence. Then find the 100th term. 35, 36, 37,...
Dmitry [639]

Given expression is 35, 36, 37, 38...

First term a = 35

Common difference d = 36-35 = 1

Nth term of arithmetic sequence is:

n_{th} = a+ (n-1)d

n_{th}= 35+(n-1)(1)

n_{th} = 34+n

To find the 100th term, substitute n = 100

n_{100} = 34 +100

n_{100} =134

Correct option is B

Solve the inequality: 4k-(5+3k)>2
Elanso [62]

Answer:

k > 7

Step-by-step explanation:

Given the inequality statement:  4k - (5 + 3k) > 2

Distribute -1 into (5 + 3k):

4k -5 - 3k > 2

Next,  add like terms:

k - 5 > 2

Add 5 to both sides of the inequality:

k - 5 + 5 > 2 + 5

k > 7

Factor out 9 and 10

9 = 3 · 3   10 = 2 · 5

Next multiply 3 by 2

3 × 2 = 6

Then multiply 3 by 5

3 · 5 = 15

Can someone please help me find the side length area, and please draw the shape on how it would look if it were finished
Mumz [18]

The side length is 5 units, and the area is 25 square units

<h3>What are areas?</h3>

The area of a shape is the amount of space it occupies

<h3>What is the area of a square</h3>

The area of a square is the product of its dimensions

From the graph, the coordinates of the square can be assumed to be:

A = (0,0)

B = (4,3)

The side length of the square is then calculated using the following distance formula

d = \sqrt{(x_2- x_1)^2 + (y_2 -y_1)^2}

So, we have:

AB = \sqrt{(0 - 4)^2 + (0-3)^2}

AB = \sqrt{25}

AB = 5

The area of the square is the calculated as:

Area = AB^2

This gives

Area = 5^2

Area = 25

Hence, the side length is 5 units, and the area is 25 square units

See attachment for the diagram of the shape
