Linear-1,2,3,6

Nin-Linear-4,5

Step-by-step explanation:

A linear equation is an equation in which the highest power of the  variable is 1.

Out of the given equations, the following are linear.

1)

2)

3)

6)

These equations on the other hand are nonlinear.

4)

5)

No 4 contains a term which is the product of two variables therefore it is not linear.

No 5 contains a term whose highest power is 3. Such an equation is a Cubic Equation.

175

step-by-step explanation:

2 inches x 10 miles = 200 miles - 3 inches = 175

answer4 to the second power is 16

and 4 to the third power is 64,
