What are algebraic expressions?A logarithmic articulation is a numerical expression that incorporates factors, constants, coefficients, and mathematical tasks. To increase two logarithmic articulations, we duplicate each term of the main articulation with each term of the subsequent articulation and join every one of the items. In a mathematical articulation, a term might comprise of a steady, one variable, a result of at least two factors, a result of both the variable and consistent part. Moreover, the mathematical terms can be both positive and negative. There are significantly three sorts of mathematical articulations.

Jovani has 144 feet of fencing to make a rectangular garden in his backyard. he wants the length to be 32 feet more than the width. find the width.
The width of rectangular garden comes out to be 20 feet .
Let the width be x feet .
Therefore , length is ( x + 32 ) feet .
Formula for perimeter of a rectangle :
perimeter = 2 ( length + breadth )
By substituting the values in the formula above , the equation becomes ,
2 ( x + x + 32 ) = 144
2 x + 32 = 144 / 2
2 x = 40
x = 20

Choose the correct answer below.
OA. If the side of a square measures 3 decimeters, then the side's measure is 30 centimeters.
OB. If the side's measure is 30 centimeters, then the side of a square measures 3 decimeters.
If the side's measure is 30 centimeters, then the side of a square measures 3 decimeters, is the "if-then" form of A side of a square measures 3 decimeters if the side's measure is 30 centimeters.
A statement with an assumption and a conclusion is known as a conditional statement (also known as an if-then statement). The hypothesis is the initial clause, or "if," part of a conditional statement which is followed by the second, or "then," component of a conditional statement is the conclusion.

The required probability is [tex]\frac{1}{10}[/tex].
This problem is related to probability.
First we have to calculate the number of outcomes and then the number of favorable outcomes.
In this case the numbers are from 1 to 150.
First we have to find the numbers which are perfect square between 1 to 150= {1,4,9,16,25,36,49,64,81,100,121,144}
Now we have to find the numbers which are perfect cube other than those which came in square={8,27,125}
Here the number of favorable outcome is 150 minus number of elements in set of perfect square and perfect cube.

An airline charges an extra fee for a checked bag that weighs more than 50 pounds.
Your bag weighs 44.9 pounds.
You have a 2.5 pound hair dryer, a 1.3 pound souvenir, and a 3.6 pound pair of boots.
Which items can you add to the bag without paying the extra fee?
you can choose any of the 3 items, or any combination of two of the items unless the hair dryer and the boots, because the combined weight is 3.6lb + 2.5lb = 6.1 lb
Which items can you add to the bag without paying the extra fee?
The maximum weight that your bag can have is 50 pounds.
The actual weight of your bag is 44.9 pounds, so if we define x as the weight you can add, then we can write the inequality:
44.9 lb + x ≤ 50lb
Solving the inequality for x, we get:
x ≤ 50lb - 44.9 lb
x ≤ 5.1 lb
Now, the weight of the items are:
hair dryer = 2.5 lb
souvenir = 1.3 lb
boots = 3.6 lb
So you can choose any of the 3 items, or any combination of two of the items unless the hair dryer and the boots, because the combined weight is 3.6lb + 2.5lb = 6.1 lb

We know that if all angles of a triangle are congruent, the angles must be as well. CPCTC (Corresponding Parts of Congruent Triangles are Congruent)
We also know that all interior angles of a triangle add up to 180 degrees. If they are all equal this only leaves us with the possibility of every angle equaling 60 degrees, otherwise they wouldn't add up to 180 AND be equal simultaneously.
To find the value of a set the equation equal to 60.
[tex]4a-8=60[/tex]
Solve for a:
[tex]4a-8=60\\4a=68\\a=17[/tex]
19:
We know in a parallelogram all interior angles sum to 360 degrees.
Remember the sum of angle pairs between parallel lines is 180 degrees. Meaning if we add angles T and S and set them equal to 180 degrees we can then find the value of angle S as we would have the value of variable x.
[tex](4x+1)+(3x+4)=180\\7x+5=180\\7x=175\\x=25[/tex]
Now substitute in the known value of x to find angle S:
[tex]3(25)+4\\75+4\\79[/tex]
Angle S measures 79 degrees.
Using our previous knowledge of two angles on a parallel line summing to 180 degrees, we can find the measure of angle R by subtracting 79 from 180.
[tex]180-79=x\\101=x[/tex]

The sum of two odd integers is an even integer. Therefore, the set S is not closed under addition.
The following subsets of Z (with ordinary addition and multiplication) satisfy all but one of the
axioms for a ring. In each case, which axiom fails?
(a) The set S of odd integers.
• The sum of two odd integers is an even integer. Therefore, the set S is not closed under addition.
Hence, Axiom 1 is violated.
(b) The set of nonnegative integers.
• If a is a positive integer, then there is no solution of a + x = 0 that is also positive. Hence, Axiom
5 is violated.
In general, to show that a subset S of a ring R, is a subring of R, it is sufficient to show that
(i) S is closed under addition in R
(ii) S is closed under multiplication in R;
(iii) 0R ∈ S;
(iv) when a ∈ S, the equation a + x = 0R has a solution in S.
Let a, b, c ∈ S ⊂ Z with a = rk, b = sk, c = tk.
(i) a + b = rk + sk = (r + s)k ∈ S
(ii) ab = (rk)(sk) = (rsk)k ∈ S
(iii) 0Z = 0 = 0 · k ∈ S
(iv) a = rs ∈ S ⇒ x = −rs ∈ S is a solution ofa + x = 0S
