Answer:
LN = 66 cm
Step-by-step explanation:
The 3 parallel lines divide the 2 sides they intersect in proportion, that is
= , substitute values
= ( cross- multiply )
15LM = 315 ( divide both sides by 15 )
LM = 21
Hence
LN = LM + MN = 21 + 45 = 66 cm
Object a:
perimeter is all the sides added together!
9+9=18
4.1+4.1= 8.2
18+8.2=36.2
object A’s perimeter is 36.2 CM

object b:
7.2+3+ 3.6= 13.8
object B’s perimeter is 13.8 CM

Answer:
b
Step-by-step explanation:
The equation is
(A ≠ B)
A is the first number, ratio, rate, etc. , and B is the second.
The ≠ symbol means "does not equal", so the equation means:
[ Ratio A is NOT equal to Ratio B. ]
