It wants expanded form and the distributive property (something like 2(5+6b), so I would think it wants something like 7(200+50+6). This way, you're multiplying 7 by each expanded part of the number, which you would do anyway when solving like normal. Please correct me if I'm wrong!
Answer:

Step-by-step explanation:
We start with the equation
. First, we multiply both sides by
.

Next, we divide both sides by
to get our answer:

Given :
On a map with a scale 1: 25000 .
The area of a lake is 33.6 square centimeters.
To Find :
The actual area of the lake.
Solution :
Let, actual area of lake is A.
So,

We know , 
Area in km² is :

Hence, this is the required solution.
Answer:
2. Line RT = 11x - 17, Line PT= 5x + 13
11x - 17 = 5x + 13
11x - 17 = 5x + 13
-5x. -5x
6x - 17 = 13
+17. +17
6x= 30
÷6. ÷ 6
x = 5
(B). According to the rules of a parallelogram, if angle S is 50°, the angle on the same side will be supplementary to it. So, angle R equals 130° and angle Q is also 50°.
Answer:
The scale factor is 5 because the increase in each side of the shape is *5
