To understand the algebra, go through the following equations below:

  • First the thing to note is that the top square is the square of the bottom square: Stage 1: 1 & 1^{2} , stage 2 = 2 & 2^{2}, stage 3 = 3 & 3^{2}
  • Second image: Just add the two values above to get the total of tiles needed.  For stage 5: 5 + 5^{2} = 30, Stage 12: 12 + 12^{2} = 156

Part B

  • First equation : y = n^{2} + n
  • second equation: y = n + (n*n)

<h3>Meaning of algebra</h3>

Algebra is defined as a branch of mathematics that deals with variables, symbols and finding of these unknown using arithmetic operation such as ( +,  -,  *,  ÷ )

Algebra is the study and understanding of mathematical symbols and how to manipulate them in mathematical problems and formulae.

Y=-4x unit rate/constant/slope<br><br>8TH GRADE
Solnce55 [7]

9514 1404 393

Answer:

  -4

Step-by-step explanation:

In a linear equation, the terms "unit rate", "rate of change", "constant of proportionality", and "slope" all refer to the coefficient of x (the independent variable).

Here, the coefficient of x is -4.

The slope is -4.

_____

<em>Additional comment</em>

Strictly speaking the "constant of proportionality" only refers to the x-coefficient (k) when the equation is of the form ...

  y = kx . . . . . with no added constant

"Slope", "unit rate", and so on, can also refer to the x-coefficient (m) when the equation has a non-zero y-intercept (b):

  y = mx + b
