Let say the number = x
double my number and add eight, I get my number plus twelve
double x and add eight, I get x plus twelve
2x + 8 = x + 12 (subtract x from each side)
2x - x + 8 = 12
x + 8 = 12 (subtract 8 from each side)
x = 12 - 8
x = 4
Your number is 4

Answer:
The perimeter is 44cm.
Step-by-step explanation:
The perimeter is the length of all the sides. So, to calculate the perimeter, add all the sides together.
However, there are two sides that do not have a measure written. So we must first calculate them:
The long vertical side can be calculated by subtracting the other vertical sides by the long bottom side:
14 - 5 - 6 = 3cm
The missing horizontal side can be found by subtracting the leftmost side by the shorter horizontal sides:
8 - 3 - 2 = 3cm
Now, add them all together:
8cm + 5cm + 3cm + 3cm + 3cm + 6cm + 2cm + 14cm = 44cm
