Option D equal is your answer ☺️☺️☺️
if the figures perimeter is 18 units, and the width of the figure is 5 units. I am guessing the figure is a rectangle
where the width is 5 units, and 2 of the sides have 2 be the same 2 be a rectangle, than the width on each side is 10 units all together
18-10= 8
if the figure is a rectangle then that means there are 2 sides left of equal length so if we divide our current number (8) by 2 then we will have the length of each side (4)
8 divided by 2= 4
width= 5
length= 4
There are 4 sides so add 4 sides
3x-4+3x-4+2x+3+2x+3=78
Combine like terms
10x-2=78
Add 2 to each side of the equation
10x=80
Divide by 10
X=8
Enter x into equation
3(8)-4=20
2(8)+3=19
Multiply by 2
20 x 2= 40
19 x 2 = 38
40 +38 =78
Side 1- 20
Side 2- 19
Side 3- 20
Side 4- 19
negative number taken to an odd power gives a negative result (because, after cancelling, there will be one minus sign left over).
