Answer:
4x^2 + 12x + 9.
Step-by-step explanation:
(2x+3)^2
= (2x+3)(2x+3)
= 2x(2x+3)+3(2x+3)
= 4x^2 + 6x + 6x + 9
= 4x^2 + 12x + 9.
Option D is correct. The correct option for the recursive formula is 
Given the sequence 10, 14, 18...
The first term is 10, hence
a1 = 10
The previous terms will be 
From the sequence, we can see that <em>4 is being added to the previous term to get the next term</em>. Hence the nth term will be expressed as:

Get the term before the first term 
If n = 1

Hence the correct option for the recursive formula is

Answer: 1. A. y=17x
2. $59.50
Step-by-step explanation:
1. In the table , it can be seen that as x increases y increases with the proportionality constant k =
,.
Equation of direct variation between x and y : 
Put k= 17 , we get
, which is the required equation.
So correct option is "A".
2. To find : The charge for renting a machine for 3.5 hours.
Put x= 3.5 in above equation , we get

Hence, the charge for renting a machine for 3.5 hours is $59.50.
So correct option is "B".
Solution :
Nominal variable
A nominal variable is defined as a variable which is used to
which are being measured.
An ordinal variable is the one in which the order matters, but the difference between any two orders does not matter.
In interval ratio variable is defined as the variable where the difference between any two values is meaningful.
The level of measurement for each of the following are :
1) Variables that are categorized in categories so that it is ordinal data.
2) Data scaled with the two categories her or his, so it is a nominal data.
3) Number of votes categorized in the intervals so it is Interval type data.
4) nominal data.
Answer:
each square takes up a 10 by 10 square is you divide it into to four pieces then you use the formula for area of a circle
Step-by-step explanation:
1) 10 x 10
Find the diameter which is 5
Use the area equation Pie r squared
Divide the diameter by 2 to get radius
3.14 x 2.5 squared
19.625
at that 4 times
You get are of circles
And Shaded area is 19.625
