a) 52 b) −28 c) 2√17 d) −2√17

Equation to determine the lengths of Aseem's and Stana's cars is:

1. 2x − 5 + x = 20

Step-by-step explanation:

Let length of Aseem's car= x

Stana's car is 5 less than 2 times the length of Aseem's car.

i.e. Length of Stana's car= 2x-5

The sum of the lengths of both cars is 20 inches.

i.e. 2x-5+x= 20

Hence,  equation to determine the lengths of Aseem's and Stana's cars is:

1. 2x − 5 + x = 20
