Answer:
x = 5/7
Step-by-step explanation:
(7^x)^4) = 7^2 * 7^3 / 7^3x
1. Simplify the expression
(7^x)^4) becomes 7^4x
7^2 * 7^3 becomes 7^5
7^5/7^3x becomes 7^5 - 7^3x
Your new equation: 7^4x = 7^5 - 7^3x
2. Since the bases(7) are the same set the exponents equal to each other
4x = 5 - 3x
3. Combine like terms
4x + 3x = 5
7x = 5
4. Divide both sides by 7 to get x by itself
x = 5/7

Answer
the space would unknow between each side of the rug and the wall
Step-by-step explanation:
because we don't know how big the room is and what the shape of the room is we have no idea what the answer will be it could be a little less than the distance around the world or it could be no distance cause it is the same size as the room
(also the rug is in the middle of the the room)
The unknown angles are in a ratio of 7 to 13.
Let 7x represent the smaller measure.Then, 13x represents the larger measure.
7x + 13x + 140 = 180
20x + 140 = 180
20x = 40
x = 2
7x = 7 * 2 = 14
13x = 13 * 2 = 26
The measures are 14 degree and 26 degrees.
