A^2 + B^2 = c^2
12^2 + b^2 = 20^2
144 + b^2 = 400
-144 -144
b^2 = 256
sqrt(b^2) = sqrt(256)
b=16
x=16
You’re using the Pythagorean theorem to solve for this where (a) represents a side of triangle, (b) represents another side and (c) represents the hypotenuse.

You have 2in = 24 mi or we can say 2in / 24mi You need to convert from miles to inches. so set up the conversion factor 2in /24mi
* = multiply
48 mi * 2in / 24mi =
96 in / 24 =
4
On the map it is 4in apart
Answer:
Define two roughly identical sets.
Reduce the chance of bias.
Step-by-step explanation:
In this experiment, Daniel performs a random assignment in order to stablish two separate groups with roughly equivalent ability to do barbell curls. Two different treatments (verbal encouragement and silence) are then applied in order to verify for a cause and effect relationship. If the groups were not randomly assigned, then the experiment could be biased.
Note the equal sign. What you do to one side, you do to the other. Isolate the x.
Subtract 4 from both sides
x + 4 (-4) = 11 (-4)
x = 11 - 4
x = 7
7 is your answer for x.
