X=3 do you need the working out ?
Answer: 2x + 0.5 unit
Step-by-step explanation:
A square has 4 equal sides. Therefore, its perimeter is calculated by adding the four sides.
Since the perimeter of a square is 8x +2 units, to get the length of one side, we divide the perimeter by 4. This will be:
= (8x + 2)/4
= 2x + 0.5
Therefore, the length of one side is 2x + 0.5 unit
They all have 4 sides, there are 2 shorter sides and 2 longer sides and the two short sides are parallel to each other, and the two long sides are parallel to each other.
Answer:
D
Step-by-step explanation:
note that the values in the domain map to the values in the domain as
- 1 → 2 ( that is 1 + 3 = 2 )
3 → 6 ( that is 3 + 3 = 6 )
5 → 8 ( that is 5 + 3 = 8 )
In each case 3 is added to the value in the domain(x) to obtain the value in the range ( y = f(x) )
Hence f(x) = x + 3 → D
The correct answer is the second option: plus or minus square root of 20
Hope this helped :)
