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 ( +, -, *, ÷ )
Algebra is the study and understanding of mathematical symbols and how to manipulate them in mathematical problems and formulae.
In conclusion, the above are the solution to the questions on the attached image.

Answer:
y = -x -1
<em><u>Brainliest, please!</u></em>
Step-by-step explanation:
(4, -5)(-6, 5)
y = mx + b
m = slope, b = y-intercept
m = 10/-10
m = -1
y = -1x + b
We can plug in (4, -5):
-5 = -1(4) + b
-5 = -4 + b
b = -1
y = -x - 1
Answer:
It is probably equal to 100 degrees, but you have not given the context of the problem.
Answer:
a) 336
b)6
c)6
Step-by-step explanation:
a) In the 1st place fit 8 cars, in the 2nd only fit 7 cars, because one is already in the first place and 3th fit 6 cars, so all the possibilities are 8*7*6.
b) in the 1st place fit 3 cars, 2nd 2 cars and 3th 1 car, so all the possibilities are 3*2*1
c) every shirt can be matched with 1 pair of pants, there are 2 shirts and 3 pants, so all the the possibilities are 6+6.
<h2>
Explanation:</h2>
We know some facts:
- There is a toll plaza every 12 1/2 miles along a 300 mile road.
- At each toll plaza drivers must pay $1.25.
First of all, we have to convert the mixed fraction into improper fraction:
Next, let's calculate the total number of toll plaza along the way:
As in every toll plaza, the driver must pay $1.25 then the total cost to drive the whole length of the road is:
