A perfect square means that all side are EXACTLY equal. I hope this helps!
Step-by-step explanation:
In number theory, a perfect number is a positive integer that is equal to the sum of its positive divisors, excluding the number itself. For instance, 6 has divisors 1, 2 and 3, and 1 + 2 + 3 = 6, so 6 is a perfect number

What is the slope and the y-intercept for the
equation = −2 − 2?
Answer:
So the slope is -2 while the y-intercept is -2
Step-by-step explanation:
y=mx+b
so you need to rearrange it so it will be
y=-2x-2
So m is slope so it is -2
and -2 is b which is the y-intercept so it is -2

Sam ordered some books online for $5 each. He paid a total of $4 for shipping. The total cost of the purchase was $89. How many books did he buy?
Part a is the equation and part b is the total
Answer:
17
Step-by-step explanation:
if you subtract 4 from 89, which is the shipping cost. 89 - 4 = 85. Then divided 85 by 5 because that will show how much he paid for them in total, by how much a singular book is. Telling you how many books he bought. 85/5 = 17.
Answer:
A.) 5b+4=89
B.) 17 books
Step-by-step explanation:
To find A.), we must create a linear equation. Let b be the number of books Sam ordered. We write 5b because each book is 5 dollars. Then we add 4 dollars to the equation to represent the shipping fee. Then we write "equals to 89", because it says that is the total cost. So we get the equation 5b+$4=$89
To find B.), we must solve the equation. Isolate the variable, by subtracting 4 from both sides. We then get 5b=$85. Now we divide by 5 to get only the variable and to get rid of the coefficient. We get b=17. So Sam bought 17 books.

What is the relationship between length of side of triangle and their interior angle ?Relationship of sides to interior angles in a triangle
In any triangle:
The shortest side is always opposite the smallest interior angleThe longest side is always opposite the largest interior angleAccording to the question
Side opposite to smallest ∠20° = OD
Side opposite to largest ∠110° = DE
Side opposite to intermediate ∠50° = OE
Now,
according to the relationship between length of side of triangle and their interior angle
The smallest side is opposite the smallest angle, and the longest is opposite the largest angle, then it follows that since a triangle only has three sides, the midsize side is opposite the midsize angle.
Therefore,
OD = smallest side
DE = Largest side
OE = intermediate side
Hence, The side with intermediate length is OE .
