Answer:
A.
Step-by-step explanation:
Graph B must be incorrect as this is a directly proportional relationship. Likewise, graph C shows an inversely proportional relationship.
Between graph A and D, only graph A passes through the origin, which is true because if length is zero, perimeter is zero.
Hence the answer is Graph A.
Answer:
77
Step-by-step explanation:
7 (3 + 2*4) =
7 (3 + 8) =
7 (11) =
7 * 11 =

Answer:
Option B is correct that is false.
Step-by-step explanation:
We have been given a figure we need to tell that the two lines are perpendicular
Lines are perpendicular if they meet at right angle.
Line 
is perpendicular to 
vice-versa is not true.
Hence, Option B is correct
Answer:
c. 92,598
Step-by-step explanation:
20000 + 20000/1.04 + 20000/(1.04^2) + 20000/(1.04^3) + 20000/(1.04^4)= 20000 + 19230.77 + 18491.12 + 17779.73 + 17096.08
= 92597.
= 92,598
Perimeter = length * 2 + width * 2. x = width. 2x = length. perimeter = 2(x) + 2(2x). perimeter = 2x + 4x. 60 (perimeter) = 6x. divide both sides by six. x = 10. width = 10. length is 2(width), so length is 20.
