I need help with this

J=

K=

L=

M=

J = (-8, 16), K = (20, 12), L = (12, -8), M = (-12, -12)

Step-by-step explanation:

Since the dilation is centered at the origin, we can multiply every coordinate by 4 to find the answers.

J = (-2 * 4, 4 * 4) = (-8, 16)

K = (5 * 4, 3 * 4) = (20, 12)

L = (3 * 4, -2 * 4) = (12, -8)

M = (-3 * 4, -3 * 4) = (-12, -12)

341

step-by-step explanation:

all you have to do is 9x31 (which equals 279) and then 20x31 (which equals 620). then you have to subtract. 620-279=341.
