325(324-323) can you me solve this problem

So you do the parentheses first.
324-323 = 1.
Since there is no sign by the parentheses and the other number you multiply.
1 x 325 = 325
So your answer is 325

You can use BODMAS, it is a acronym that stands for: brackets, orders, division, multiplication, addition, subtraction. This is a general order to see what parts of a equation you solve;

We can see there is a bracket, so we solve that first;
(324-323) = 1

Then numbers next to brackets just means we multiply them, so...
325(1) = 325*1 = 325

Hope this helps! :)

Given that ABC is a triangle and is reflected over the y - axis, reflected over the x - axis and rotated 180°

We need to determine the coordinates of the point A'

Reflection over the y - axis:

The coordinates of the point A is (-2,1)

The transformation rule to reflect across the y - axis is

Substituting the point (-2,1) in the rule, we get;

Thus, the coordinates of the point A after reflection over the y - axis is (2,1)

Reflection over the x - axis:

The transformation rule to reflect across the x - axis is

Substituting the point (2,1) in the rule, we get;

Thus, the coordinates of the point A after reflection over the x - axis is (2,-1)

Rotation about 180°:

The transformation rule to rotate about 180° is

Substituting the point (2,-1) in the rule, we get;

Thus, the coordinates of the point A after the rotation about 180° is (-2,1)

Therefore, the coordinates of the point A' is (-2,1)

Hence, Option B is the correct answer.
