Answer:
Step-by-step explanation:
Given:
We need to reduce the given matrix to reduced echelon form.
Solution:
Make zeroes in column 1 except the entry at row 1, column 1. As we can see all elements in column are already zero. Make zeroes in column 2 except the entry at row 2, column 2.
So, in reduce echelon form is
By definition a square has all 4 sides equal, the area of a square is sxs or s^2, so s^2 = 400, s = square root of 400 = 20. All sides will be equal to 20 m. The perimeter is the sum of the sides or 4 x s or 80.
Steps:
A= L^2
Where L is length of the side
400=L^2 》》》》》 square root
L= 20 all sides of square are 20 m
P = 4L
=4(20)
=80m
So,we know that it take 0.8 of a minute or 48 seconds to read each page of a health book, so it will take 300 seconds to read 6.25 pages. As a result, it will take 10.5 minutes to finish reading 6.25 pages and also taking a test. Hope it help!
