Answer:
bottom left
Step-by-step explanation:
line of symmetry means that both sides will look the same if a line is drawn thru
Answer:
4x - 12 = 28
To isolate 4x, we add 12 to both sides:
4x - 12 + 12 = 28 + 12
so
4x = 40
Now we divide 4 from both sides:
x = 40 / 4
so x = 10
Answer:
x = 27
Step-by-step explanation:
The angle at any point on a straight line is 180 degrees.
The middle line over there is creating a right angle which is 90 degrees.
This must mean that both sides are 90 degrees.
3x+9 = 90
3x = 81
x = 27
I don’t know I don’t have the smarts for that lol
Answer:
P = 6x-2
x = 14
Step-by-step explanation:
To find the perimeter, we add the sides
P = 4x-8 + 3-2x + 5x+3
Combine like terms
P = 4x-3x+5x -8+3+3
= 6x -2
Now we know the perimeter
82 = 6x-2
Add 2 to each side
82+2 = 6x-2+2
84 = 6x
Divide each side by 6
84/6 = 6x/6
14=x
