the equation would be E=10h+15
1=25
2=35
3=45
4=55
Perimeter = 10 × 9 1/3 m
since , Decagon have 10 sides
perimeter = 280/3 m

Answer:
x = 14
Step-by-step explanation:
Assuming the triangles are similar then the corresponding sides are in proportion, that is
= = ( cross- multiply )
3(x - 4) = 30 ( divide both sides by 3 )
x - 4 = 10 ( add 4 to both sides )
x = 14
3x + 6 = 12
First operation was subtraction (subtracting 6 to leave 3x alone)
Second operation was division (Dividing 3 from 3x to isolare x)
3x + 6 = 12
3x + 6 -(6) = 12 - 6
3x = 6
=
3 and 3 cancels out
x = 2
