Distribute the h:
h(h+4)
h*h + 4*h
h² + 4h
Hope this helps!
The answer is 14 bolts.
1 dozen bolts have 12 bolts.
7 dozen bolts have x bolts
___
1 : 12 = 7 : x
x = 7 * 12 : 1
x = 84 bolts
1 bin has 7-dozen bolts (84 bolts).
1/6 bin has x bolts
1 : 84 = 1/6 : x
x = 84 * 1/6 : 1
x = 84/6 = 14 bolts
4X + 8 9X+3 (this is the equation, nothing to explain in this step)
4x + 5 = 9x (you combine or subtract the like terms, 8 - 3 = 5)
5 = 5x (you do 9x - 4x = 5x, subtracting the like terms)
1 = X (your answer after dividing 5 from both sides)
From the given data, it is clear that the first area model represents the fraction 
From the second area model,
Total number of regions = 6
Number of shaded regions = 2
The fraction represented by the model =
