What is the value of this expression when w=-5? W^2 + 3w- 11

A. -51
B. -36
C. -16
D. -1

D. -1

Step-by-step explanation:

w^2+3w-11, w=-5

(-5)^2 + 3*(-5) - 11

= 25 - 15 - 11

= 25 - 26

= -1

D.)  -1

Step-by-step explanation:

W∧2 + 3w - 11

since w=-5,

(-5)∧2 + 3(-5) - 11

25-15-11

-1

the answer is (2x+8)²= 16

for the friend request.

when a figure, such as triangle (xyz) is reflected over the line y = x to create x'y'z' the x-coordinates and y-coordinates of the original image (pre-image) will be reversed for the image. (e.g., (x, y) > (y, x)) this means that the pre-image position of the x- and y-coordinates switch places which in turn provides a mirror like image of the original xyz.  

i notice that when i draw a line segment from x to x', that the points are parallel from each other -- they are exactly across from each other and do not intersect with any other points.  

yes, think i would see the same characteristic if you drew the line segment connecting y with the reflecting line and then y' with the reflecting line because of the essence of reflections. because it is a mirror image, each point was effected the same way which leads me to conclude that they same would apply to y and y'.
