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 &
, stage 2 = 2 & 
, stage 3 = 3 & 
- Second image: Just add the two values above to get the total of tiles needed. For stage 5: 5 +
= 30, Stage 12: 12 + 
= 156
Part B
- First equation : y =
+ 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 ( +, -, *, ÷ )

Answer:
our inputs are 3 & 1/2
Step-by-step explanation:
the ? is the slope and the slope is equal to 1/2 so
?=1/2
the point slope formula is
(y-y1)=m(x-x1) (x1,y1)--> a point on the line m--> slope
so we chose (x1,y1) as (3,0)
when we plug that in we get
y-0=1/2(x-3)
so our inputs are 3 & 1/2
Step-by-step explanation:
Original price- $250
Discount 20% x 20
-----------
5000
Equals amount taken off $5000
Subtract original price -250
---------------
Sale Price 4750
Hope this helps! If this is not the answer please tell me!
It is the last one. A closed circle means less than or equal to, so that crosses out the top two. The third says five is greater and we know that is not true because the line is decreasing in value. It must be the fourth.
Answer:
131.15
Step-by-step explanation:
- 157.38÷6=B
