Simplify the following expression. 3x4 +2x3 - 5x2 + 4x2 +6x-2x - 3x4 + 7 x - 3x3​
vlada-n [284]

<u><em>**I want to mention that please use asterisk (*) symbol for multiplication as multiplication symbol x and variable x look the exact same</em></u>

Your question is

3*4+2*3-5*2+4*2+6x-2x-3*4+7x-3*3

First calculate each term getting

=12+6-10+8+6x-2x-12+7x-9

Now combine like term which means adding all of the constant together and all of the term containing variable x together

=11x-5

Therefore 11x-5 is the answer to the expression.

Rectangle KLMN is graphed on the coordinate plane below. On a coordinate plane, rectangle K L M N has points (2, negative 2), (5
gladu [14]

Answer:  The correct option is (A) (2, -2).

Step-by-step explanation:  Given that rectangle with vertices at K, L, M and N is graphed on the coordinate plane as shown in the figure.The figure is rotated 360° counterclockwise using the origin as the center of rotation.

We are to find the location of the image of point K after the rotation.

We know that

a rotation of 360° in counterclockwise direction about the origin map a point to itself. That is, the co-ordinates of the image point will be same as the original one.

From the figure, we see that the co-ordinates of point K are (2, -2).

Therefore, after rotation of 360° counterclockwise using the origin as the center of rotation,

the co-ordinates of the image of point K will also be (2, -2).

Thus, the location of the image of point K is (2, -2).

Option (A) is CORRECT.
