Rhombus wxyz is graphed on a coordinate plane. what is the perimeter of the rhombus? 16 units 20 units 24 units 28 units

see diagram in attachment

a rhombus is a 4 sided figure with 4 equal length sides

so if we can find the length of 1 side and multiply it by 4, we get the perimiter

you can draw 2 lines to make 4 similar triangles

we can see that you can use pythagorean rule to get the length of the hypotonuse of one triangle so so perimiter is 4*5=20 units

or you can use distance formula which is basically the pythatorean theorm

from W to X, that is from (-3,1) to (1,4)

4*5=20, so perimiter is 20 units

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
