Ruth decides to test the method of proportions and similar triangles to find the height of a tree. She decides to again find the
height of a tree she had measured earlier in the day at 10 A. M. This
time, she decides to use this method at 5 P. M. in the evening. She
measures the length of the tree's shadow and finds it to be 48 feet
long this time. Then she holds a 12-inch ruler perpendicular to the
ground and finds that it casts a 24-inch shadow. How tall will she find
the tree?
a. 6 ft c. 48 ft
b. 24 ft d. 288 ft

(x+3)(x+7)

step-by-step explanation:

answer:

it is general formula that is used to write value to its excet position

a11 a12 a13

a21 a22 a23

it is the example of order 2 by 3 matrix in this

a11 means value occur in 1 st row 1st column

a12 means value occurs in 1st row 2nd column

a13 means value occur in 1st row and 3rd column

a21 means value occurs in 2nd row and 1st column

a22 means value occurs in 2nd row and in 2nd column

a23 means value occurs in 2nd row and in 3rd column
