Answer: it should be 34.5
Step-by-step explanation:
Answer:
Option 2: 2x + 2 = 72
Step-by-step explanation:
First odd: x
Next odd: x + 2
x + (x + 2) = 72
2x + 2 = 72
Because the difference between two consecutive odd numbers is 2.
e.g 3 and 5
They are NOT similar because similar triangles have congruent angles, but are different sizes. These angles are not congruent.
Let

be a rectangular

matrix with column vectors

, i.e.

Then we have

and the product of the two is

Because the columns of

are orthonormal, we have

which means

reduces to an

matrix with ones along the diagonal and zero everywhere else, i.e.

where

denotes the identity matrix. This means the solution to

is given by
D = √(x2 - x1)^2 + (y2 - y1)^2) =
= √(6 + 1)^2 + (-2 - 4)^2) =
= √ (7^2 + 6^2) =
= √(49 + 36) =
= √85
