Answer:
B and C
Step-by-step explanation:
Answer:
the coefficient is 2
Step-by-step explanation:
The slope of XY is the same as the slope of AB because AB is parallel to XY and parallel lines have the same slope.
A square has all the sides being equal.
Since the top can fit 3 color tiles, then the side must fit the same number of tiles.
Therefore, 3 roles and 3 columns of tiles will be required.
The number of tiles required will calculated similar to area of a square. That is,
Number of tiles = 3*3 = 9 tiles.
You can put the numbers where the variables are and do the arithmetic, or you can simplify the expression first. In the latter case, you have
(3a^(-2-(-1))b^(6-5)/2)^2 = (3a^(-1)b^1/2^2 = (3b/(2a))^2
= (3(-2)/(2(3)))^2 = (-1)^2 = 1
The value of the expression is 1.
