lines a and d are parallel and lines b and c are parallel
Answer:
5 vertices
Step-by-step explanation:
At base = 4 vertices
On top = 1 vertex
Total = 5 vertices
For rhombus A:
base = 7 in
area = 35 in²
Area of rhombus = b * h
⇒ 35 = 7 * h
⇒ h = 35/7
⇒ h = 5 in
Rhombus B:
height = 3*5 = 15 in
base = 7*3 = 21 in
Area = 15 * 21 = 315 in²
Area
of rhombus B is 9 times area of rhombus A. When the dimensions are
increased to 3 times the initial dimension, area became 9 times.
X=3
g(3)=3+4=7
f(g(3))=f(7)=78
f(g(3))f(g(3))=6084
is this the correct answer?
