Answer:
X=15
Step-by-step explanation:
Ignore the increase for equasion. This is factored in but irellevent. Orignal x value is 13, but increases to 15, and orignal x value is not needed for this equasion. (its there to confuse you)
L+L+W+W=66.
(w+3) +(w+3) +w +w = 66
(4xw) + 3 +3= 66
4 x w = 66 -3 -3
4 x w =60
60/4= 15.
L= 15+ 3 =18
W = 15.
W + W + L + L
15 + 15 + 18 +18 =66
Answer:
$1200
Step-by-step explanation:
The clustering method for estimation is a method used for estimating the sums and products of numbers. This method is used when the numbers that are to be multiplied or added are near in value to a single number.
Given the money raised by six fund raisers:
$212, $205, $206, $190, $188, and $195
The numbers are to be added to find the total money raised. i.e.:
$212 + $205 + $206 + $190 + $188 + $195
But all the numbers are close to $200. Hence:
Using clustering method = $200 + $200 + $200 + $200 + $200 + $200 = 6 * $200 = $1200
The correct answer is: -18 .
________________________________________
9i * 2i = 18 i² .
________________________________________
" i " is an imaginary number equal to "√(-1) " .
" i² " = [√(-1)] ² = √(-1) * √(-1) = -1 .
________________________________________
18 * i² = 18 * -1 = -18 .

Step-by-step explanation:
The nth term just mean how to work out the next number in he series. In this series of numbers, you have to square three n and add it onto 10 n to do this.
N is the term- the number it comes in the sequence.
Example:
2 3 4 5 6
2= the first terof the sequence
3= second term
4=3rd term
And so on
To work out what the next term is (6th term) you use this expression:
N+1
The first term is 2. As it is the first n=1. 1+1=2 so that works
The seco d term is 3. As it is the second term n=2. 2+1+3 so that works
And so on
This might help
But you have to do the rest
