Answer: option C.) an 1.2 (n-1) -5 Sorry, no subscript for "a sub n"

Step-by-step explanation:

Substitute the values of n 1,2,3,4 and see if the output is the corresponding number in the sequence.

n = 1 2 3 4

-5 -3.8 -2.6 -1.4

an= 1.2 (n-1) -5 the n-1 needs to be a number multiplied by 1.2 produces a number added to -5 results in the number in the sequence.

a1=1.2(1-1) -5 a= 1.2(0) -5 a= -5

a2 1.2 (2-1) -5 a= 1.2(1) -5 a= -1.2 -5 a= -3.8

a3 1.2 (3-1) -5 a= 1.2(2) -5 a= -2.4 -5 a= -2.6

a4 1.2 (4-1) -5 a= 1.2(3) -5 a= -3.6 -5 a= -1.4

The factorisation of 10xᴧ2 – 18xᴧ3 + 14xᴧ4 is

ikadub [295]

Answer:

${10x}^{2} - 18 {x}^{3} + {14x}^{4} \\$

factorise out x² :

$= {x}^{2} (10 - 18x + 14 {x}^{2} )$

then factorise out 2:

$= 2 {x}^{2} (7 {x}^{2} - 9x + 5)$

What is addition and subtraction

choli [55]

$\huge\text{Hey there!}$

$\huge\textsf{What is addition \& subtraction?}$

$\huge\textbf{What is addition?}$

$\bullet\large\textbf{ Well, \underline{addition} simply means when you're ADDING}\\\large\textbf{2 or more numbers from each other to get the result of}\\\large\textbf{a number.}$

$\huge\textbf{Random notes}$

$\star\large\textbf{ Usually, you start working with addition when you're in}\\\large\textbf{pre-kindergarten (pre-k also known as head-start)}\\\\\star\large\textbf{ When, you're adding you are going upward.}\\\\\star\large\textbf{ Addition sometimes come after you learn how to count}\\\large\textbf{the basic numbers and so forth because adding never}\\\large\textbf{ends if you really think about.}$

$\huge\textbf{Example:}$

$\heartsuit\large\textbf{ 2 \boxed{\bf +} 5 = 7}\\\\\\\heartsuit\large\textbf{ You got the result of 7 because you started at 2 \& went}\\\larg\textbf{up 5 spaces to your right on your number and you landed}\\\large\textbf{on 7.}$

$\huge\textbf{What is subtraction?}$

$\bullet\large\textbf{ Well, subtraction simply means you're taking away. Often}\\\large\textbf{people call it take aways.}$

$\huge\textbf{Random notes:}$

$\star\large\textbf{ Usually, you start working with subtraction when you're}\\\large\textbf{in pre-kindergarten (pre-k also known as headstart)}\\\\\star\large\textbf{When you're subtracting you are doing downward.}\\\\\star\large\textbf{You focus more on subtraction when you're counting}\\\large\textbf{backwards.}$

$\huge\textbf{Example:}$

$\heartsuit\large\textbf{ 7 \boxed{\bf -} 5 = 2 }\\\\\\\heartsuit\large\textbf{ 7 \boxed{\bf -} 2 = 5}\\\\\\\heartsuit\large\textbf{ For equation \#1. you begin at 7 and go BACK 5 spaces}\\\large\textbf{and you should have landed on 2.}\\\\\\\heartsuit\large\textbf{ For equation \#2. you begin at 7 \& go BACK 2 spaces}\\\large\textbf{and you should have landed on 5.}$
