Answer:
To find out the first three terms of 2n + 4 substitute 1 ,2 and 3 into the equation.
2(1)+4=2+4=6
2(2)+4=4+4=8
2(3)+4=6+4=10
As you can see the sequence goes up in 3s 6 ,8, 10 To find out the 9th term you also substitute 9 into the equation so
2(9)+4=18+4=22
Hope this helped!
Answer:
perimeter = 204m
Step-by-step explanation:
area of a square = side²
2601m² = side²
√(2601m²) = √side²
51m = side
perimeter of a square = 4*side
perimeter of this square = 4*51
perimeter of this square = 204m
