Answer:
16
Step-by-step explanation:
55-7= 48
48/3 = 16
The correct answer is A. x=22
Since the angles of a rectangle are right angles (90 degrees) you would set it up as 90=5x-20. Then combine like terms and solve the equation. (If you need me to show you how step by step tell me)
Shape: the form of an object
Outline: the line by which a figure or object is defined or bounded
Center: Point that is equal distances from any point of the circle
Spread: the measure of how far the numbers in a data set are away from the mean or the median
Answer:
x=19
Step-by-step explanation:
First, you place the numbers in place of the variables in their relative positions using the pythagorean theorem:

Then you square the numbers that you currently have:

Then subtract 225 from both sides to isolate the x:

This gives you the equation:

Then take the square root of both sides which gives you:

Then round to the nearest whole number which gives you x=19
