Well in set A, all of the sides are the same length but they are different shapes.
In set B, all of the angles are the same, they are just differnet shapes.
Hope this helps! :)
<span>4(x - 3) - 5(x + 1) = 3
4x - 12 - 5x - 5 = 3
-12 - 5 - 3 = 5x - 4x
x = -20

Answer:
1:c
let x be the distance
12^2=10^(2) + x^(2)
x=6.6332
2.D
length of 2->3 and 2->1 is 90ft, they are perpendicular
by using Pythagorus theorem
the diagonal of the square = square root of the sum of 90^2 +90^2
=127.279ft
3.B
12^2 -6^2 = 10.39ft

Step-by-step explanation:
the was I understand matrix multiplication, I re-learned tonight so I could be wrong but.....
according to Gaggle matrix multiplication is possible when the number of columns in matrix 1 equals the number of rows in matrix 2
it is called the dot product (that sounds familiar)
first choice has 2 columns and 1 row can't multiple this one
second choice has 1 column and 2 rows can't multiple this one
third choice has 2 columns and 1 row can't multiple this one
fourth choice has 1 column and 1 row This one can be multiplied
