Answer:
7 miles per hour.
Step-by-step explanation:
Right now, the relationship in the problem represents 3
miles in hours. To find out what the unit rate is (number of miles per mile), we need to multiply both sides of the equation show BeLoW:
3
= 
7 miles = 1 hour
Therefore, Doug's average speed in miles per hour is 7 (7 miles per hour).

Answer:
The answer is below
Step-by-step explanation:
Two polygons are said to be congruent if they have the same size and shape that is their corresponding angles and sides are equal.
Hence since Quadrilaterals ABCD is congruent to EFGH, then their corresponding angles and sides are equal.
In quadrilateral ABCD:
∠A + ∠B + ∠C + ∠D = 360° (sum of angles in a quadrilateral)
Substituting:
47 + 39 + 112 + ∠D = 360
∠D + 198 = 360
∠D = 360 - 198
∠D = 162°
The image of Quadrilaterals ABCD and EFGH is not given but let us assume that they have the same orientation, hence:
∠A = ∠E = 47°
∠B = ∠F = 39°
∠C = ∠G = 112°
∠D = ∠H = 162°
(-4)^-3 =
-4^-3 = 
Basically in this situation there is no difference whether parenthesis are used or not.
So distributive=ab+ac=a(b+c)
so
find the gcf of 4 and 12
4=2 time 2
12=2 times 2 times \3
the gcf is 2 times 2 =4
4(d+3e)
