X-4+x=20
2x=20+4
2x=24
X=12
Number is 12 because 12-4 is 8 and 8+12 is 20
Answer: The graph is attached.
Step-by-step explanation:
The region is limited by two lines:
and 
You can write the first inequlity 
in the following form:
This region are all the values for which the y-axis is less than the line f(x)=x+6 (all the values under the line).
The other inequality x ≤ 4 are all the values for which the x-axis is less than the line x=4 (all the values to the left of the line).
Observe the graphs attached.
Answer:
Step-by-step explanation:
Anything from the center to the edge is the radius. It is one half of what it measures in diameter.
The two shorter sides of the rectangle are 5cm each and the two longer ones are 8cm each. we know this because if one of the sides of the rectangle is 5cm that means the other side is also 5cm. if you add these two sides you get 10cm. if the total perimeter of the rectangle is 26cm and you know that two sides add up to 10cm then you subtract 10cm from 26cm. this will give you a remainder of 16cm for the remaining sides in question. if the total of the two remaining sides is 16cm that means that each of the remaining sides is 8cm long because 16/2 = 8
