b. 2.2 units
c. 3 units
d. 3.2 units
*answer asap*

The correct answer is option A.

Step-by-step explanation:

Given : Polygon ABCD reflects about line MN to make polygon EFGH

To find = FG = ?

Solution.

Polygon formed by the reflection of polygon ABCD will have same measurement of length for each corresponding sides.

AB = EF = 3 units

BC = FG = 2 units

CD = GH = 2.2 units

AD = EH = 3.2 units

So, the length of FG is 2 units.

Step-by-step explanation:

I just did this on plato :))

yeah and the opposite of cheating is studying ( you should try it some time)

step-by-step explanation:

x = -3

y = -18

step-by-step explanation:

to solve by substitution, substitute one variable and solve for the other. then substitute again to find the remaining variable.

x-1/3(3x-9) = -3 since y=3x-9 substittute y.

x-1/3(3x-9)=-3

x + x +3 = -3

2x+3=-3

2x+3-3= -3-3

2x=-6

x=-3

substitute again into y=3x-9

y=3(-3)-9

y=-9-9

y=-18
