Answer:
Step-by-step explanation:
Pattern 1 consists of
small squares (here n = 1 and 
).
Pattern 2 consists of
small squares (here n = 2 and 
).
Pattern 3 consists of
small squares (here n = 3 and 
).
Thus, pattern n consists of
small squares.

Part A
<h3>Answer:
h^2 + 4h</h3>
-------------------
Explanation:
We multiply the length and height to get the area
area = (length)*(height)
area = (h+4)*(h)
area = h(h+4)
area = h^2 + 4h .... apply the distributive property
The units for the area are in square inches.

Part B
<h3>Answer:
h^2 + 16h + 60</h3>
-------------------
Explanation:
If we add a 3 inch frame along the border, then we're adding two copies of 3 inches along the bottom side. The h+4 along the bottom updates to h+4+3+3 = h+10 along the bottom.
Similarly, along the vertical side we'd have the h go to h+3+3 = h+6
The old rectangle that was h by h+4 is now h+6 by h+10
Multiply these expressions to find the area
area = length*width
area = (h+6)(h+10)
area = x(h+10) ..... replace h+6 with x
area = xh + 10x .... distribute
area = h( x ) + 10( x )
area = h( h+6 ) + 10( h+6 ) .... plug in x = h+6
area = h^2+6h + 10h+60 .... distribute again twice more
area = h^2 + 16h + 60
You can also use the box method or the FOIL rule as alternative routes to find the area.
The units for the area are in square inches.

Answer:
∠ 2 = 104°
Step-by-step explanation:
Since the trees are parallel, then
∠ 2 and 76° are same- side interior angles and are supplementary, thus
∠ 2 + 76° = 180° ( subtract 76° from both sides )
∠ 2 = 104°
