sorry don't know i just need points
GOOD LUCK
me and my friend are seeing who can get more points
Answer:
Step-by-step explanation:
To find the matrix A, took all the numeric coefficient of the variables, the first column is for x, the second column for y, the third column for z and the last column for w:
And the vector B is formed with the solution of each equation of the system:
To apply the Cramer's rule, take the matrix A and replace the column assigned to the variable that you need to solve with the vector b, in this case, that would be the second column. This new matrix is going to be called .
The value of y using Cramer's rule is:
Find the value of the determinant of each matrix, and divide:
8 for 6 is the answer I think
Answer:
A. The length is 3
B. angel T
C. The perimeter is 20ft
Step-by-step explanation:
They are congruent so there side leghths are the same.
Answer:
The width of the football field is 160 feet.
The length of the football field is 360 feet.
Step-by-step explanation:
Let w represent width of the football field.
We have been given that the length is 200 ft more than the width, so the length of the field would be .
We are also told that the perimeter is 1,040 ft. We know that football field is in form of rectangle, so perimeter of field would be 1 times the sum of length and width. We can represent this information in an equation as:
Let us solve for w.
Therefore, the width of the football field is 160 feet.
Upon substituting in expression , we will get length of field as:
Therefore, the length of the football field is 360 feet.
