Tina's age is 4 years less than 3 times her niece's age. if her niece's age is x years, which of the following expressions best shows tina's age? x − 4 4x − 3 3x − 4 4 − 3x

3x-4

Step-by-step explanation:

Given niece age is x

Also Tina's age is 4 years less than 3 times her niece age

this can be represented by

Tina's age=3x-4

Thus 3x-4 is the correct relation to show tina age.

answer: the answer is   graph (a)

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
