Answer:
The width is 5 meters
Step-by-step explanation:
The rectangular field is 24 meaning adding just one width and length of the rectangle would be 12.
x = width
2x - 3 + x = 12
3x - 3 = 12
3x - 3 + 3 = 12 + 3
3x = 15
x = 5
Answer:
658-10=648
Step-by-step explanation:

Answer: The missing length is 40 m.
Step-by-step explanation:
30^2 + b^2 = 50^2
900 + b^2 = 2500
-900 -900
b^2 = 1600
b= 40
Answer:
The twentieth term is 50.
Step-by-step explanation:
The equation that describes the arithmetic sequence describes it's "general term", which means that all the numbers in that sequence must follow that equation. For instance, if we want to find the first term of the sequence we must make a = 1 and we have:
a1 = 3*1 - 10
a1 = -7
Therefore to find the twentieth term we need to make n equal to 20. This is done below:
a20 = 3*20 - 10
a20 = 60 - 10
a20 = 50
The twentieth term is 50.
