Answer:
D is the answer
Step-by-step explanation:
B. Is a Geometric sequence
D.) Is a Arithmetic sequence
Answer:
120
Step-by-step explanation:
As x goes from 1 to 2, y increases by 4 from 4 to 8
As x goes from 2 to 3, y increases by 4 from 8 to 12
We increase by 4 each time
The formula for an arithmetic sequence is
an = a1+d(n-1)
where a1 is the first term which is 4
d is the common difference or the number we add each time which is 4
n is the term we are looking for which is 30
a30 = 4 +4 (30-1)
a30 = 4+4(29)
= 4+116
= 120
2.66666666667 is the answer
Answer:
Option D
Step-by-step explanation:
Formula to be used,
Scale factor = 
By this formula,
L = 
= 77 inches
Similarly, width of the the dilated rectangle = 
= 35 inches
Perimeter of the new rectangle = 2(Length + width)
= 2(77 + 35)
= 224 inches
Option (D) will be the correct option.
