Answer:
x = 2/7
Step-by-step explanation:
Step 1: Write equation
20x + x - 2 = 4
Step 2: Solve for <em>x</em>
- <u>Combine like terms:</u> 21x - 2 = 4
- <u>Add 2 to both sides:</u> 21x = 6
- <u>Divide both sides by 21:</u> x = 6/21
- <u>Simplify:</u> x = 2/7
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
20(2/7) + 2/7 - 2 = 4
40/7 + 2/7 - 2 = 4
42/7 - 2 = 4
6 - 2 = 4
4 = 4
The two points are on the same line on the x-axis, so to find the length we need to find the distance between the points on the y-axis. Subtract one y from the other (it doesn't matter which) and take the absolute value. 18 - (-7) = 25. The absolute value of 25 is 25. The length of that side of the rectangle is 25.

Apply a law of exponents. When multiplying you add the exponents:-
2^-3 * 2^x * 2^(x+2)
= 2 ^(-3 + x + x + 2)
= 2^(2x - 1) Answer
