How would I multiply these matrices? (I thought this would be undefined but my teacher said it wasn’t)
When we do Matrix multiplication, we keep these two conditions in mind: 1 The number of columns of the first matrix in the multiplication process must equal the number of rows of the second.
here number of columns of 1st matrix is not equal to number of rows of 2nd matrix.
To multiply two matrices, we must first determine if the first matrix's number of columns and rows equals the second matrix's number of rows. Then sum all of the results after multiplying each element of the first matrix's column by each element of the second matrix's row.
In dealing with many ideas in linear algebra, matrices are crucial. In mathematics, a matrix is a rectangular array or table with rows and columns of integers, symbols, or expressions. Matrix operations include addition, subtraction, multiplication, and other operations.

What is the approximate value of 8–√ ?
The value of 8-√5 is approximately 5.76 which is calculated by rounding the square root of 5 to 2 decimal places.
A number y whose square (the outcome of multiplying the number by itself, or y × y), is x (y² = x) is said to be the square root of a number x.
For instance, since 4² = (4)² = 16, 4 and -4 are the square roots of 16.Every nonnegative real number x has a singular nonnegative square root, denoted by √n where the symbol √ is known as the radical sign or radix, which is known as the primary square root.For instance, we write to indicate that the primary square root of √9 is 3. The radicand is the phrase (or integer) whose square root is being analyzed. The quantity or phrase that appears beneath the radical sign is known as the radicand.Now the given expression is of the form ( 8 - √5 )
We know that √5 = 2.2360... ≈ 2.24 (rounded to 2 decimal places.)
∴ 8 - √5
= 8 - 2.24
= 5.76
Hence the value of the expression is approximately 5.76 .

The approximate weights of two animals are 4.23 x 103 lbs. and 8.7 x 103 lbs. find the total weight of the two animals. write the final answer in scientific notation with the correct number of significant digits.
The total weight of two animals in scientific notation is 1.3 x 10⁴ lbs.
Scientific Notation:
A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10.
For example,
650,000,000 can be written in scientific notation as 6.5 ✕ 10⁸.
Given,
The approximate weights of two animals are 4.23 x 10³ lbs. and 8.7 x 10³ lbs.
Here we need to find the total weight of the two animals and we need to write the final answer in scientific notation with the correct number of significant digits.
The total weight of the two animals is calculated as
Total weight = Animal 1 + Animal 2
So,
Total weight = 4.23 x 10³ lbs + 8.7 x 10³ lbs.
Take 10³ lbs as the common term,
Then we get,
Total weight = (4.23 + 8.7) x 10³ lbs.
Total weight = 12.93 x 10³ lbs.
It can we rewritten as,
Total weight = 1.293 x 10⁴ lbs.
When we round off it, then we get,
Total weight = 1.3 x 10⁴ lbs.
Hence, the total weight of the two animals is 1.3 x 10⁴ lbs.

please help it’s about finding the mean
The mean of the data is 16 cm and the absolute mean deviation is 1.4 cm.
Given we have the data set values.
Total number of data set values = 10
to find the mean we need to find the sum of the data set values and then divide it by the total number of data set values.
Therefore, mean = 13₊14₊14₊16₊16₊16₊16₊18₊18₊19 / 10
mean = 160/10
mean = 16 cm
To find the absolute mean deviation we need to find the deviation from the mean, from that the absolute mean deviation.
Data value Deviation from mean Absolute mean deviation
13 13 ₋ 16 = ₋3 I ₋3 I = 3
14 14 ₋ 16 = ₋2 I ₋2 I = 2
14 14 ₋ 16 = ₋2 I ₋2 I = 2
16 16 ₋ 16 = 0 0
16 16 ₋ 16 = 0 0
16 16 ₋ 16 = 0 0
16 16 ₋ 16 = 0 0
18 18 ₋ 16 = 2 2
18 18 ₋ 16 = 2 2
19 19 ₋ 16 = 2 3
Now the total of the absolute mean deviation is 14
divide it by 10
= 14/10
= 1.4 cm
Hence we get the mean and the absolute mean deviation as 16 cm and 1.4 cm.

Solve inequality.
t+8 ≥ 19
To solve the inequality, subtract 8 from both sides. The solution is t ≥ 11 or [11, ∞)
Tips to solve linear inequalities:
Isolate the variable on one side by using subtraction or addition. Subtraction and addition will not change the inequality.Use division or multiplication to find the solution. Multiplication and division by a positive number will not the inequality. However, if we multiply or divide both sides with a negative number, we need to flip the inequality direction.Interval notation is often used for the solution(s). Recall the differences between a bracket [ or ], and a parenthesis ( or ). A bracket means the endpoint is included in the solution while a parenthesis means the endpoint is not included in the solution. Remember, infinity ∞ always use a parenthesis.
Example: x ≥ 2 can be written as [2, ∞), while
x > 0 is written as (2, ∞)
The given problem:
t+8 ≥ 19
Subtract 8 from both sides. Subtracting a number from both sides will not change the inequality. Hence,
t+8 - 8 ≥ 19 - 8
t ≥ 11
Using the interval notation, the solution is [11, ∞)

(PLS HELP I NEED THIS ITS DUE IN 30 MIN) The perimeter of the quadrilateral is 120 feet and BA = x + 30, BC = 2x + 10, and CD = x + 20. Determine the length of the sum of the smallest side and the largest side.
The length of the sum of the smallest value and the largest value is 105 feet.
Given data
BA = x + 30
BC = 2x + 10
CD = x + 20
Perimeter = 120 feet
How to find the length of the sum of the smallest side and the largest side.The perimeter refers to the sum of all the dimensions which is given as 120 feet. We sum the dimensions given to find the value of x.
This is done as follows:
Perimeter = BA + BC +CD
120 = x + 30 + 2x + 10 + x + 20
120 = x + 2x + x + 30 + 10 + 20
120 = 4x + 60
4x = 120 - 60
4x = 60
x = 60 / 4
x = 15
plugging in x = 15 into the dimensions given we have
BA = x + 30
BA = 15 + 30
BA = 45
BC = 2x + 10
BC = 2 * 15 + 10
BC = 30 + 40
BC = 70
CD = x + 20
CD = 15 + 20
CD = 35
Hence we can say that the smallest value is 35 and the largest value is 70.
sum of the values
70 + 35 = 105
The sum of the smallest value and the largest value is 105 feet.

Mariam took a taxi from her house to the airport. The taxi company charged a pick-

Write and solve an equation which can be used to determine m, the number of miles
in the taxi ride.
The equation illustrates that the number of miles will be 3 miles.
How to compute the value?The taxi company charged a pick- up fee of $2.90 plus $1.25 per mile.
Let the number of miles be m.
Therefore, this will be:
2.90 + (1.25 × m) = 6.65
2.90 + 1.25m = 6.65
Collect like terms
1.25m = 6.65 - 2.90
1.25m = 3.75
m = 3.75/1.25
m = 3
