The formula is 180(n-2)= 1140 then you divide 1140 by 180 to get 8 so then it would like like n-2=8 add the 2 over and n (being the number of sides)= 10 so your answer will be 10

hodyreva [135]

The solution of y= $2x^{2} +x$ given as:

x: 0 1 2 3

y: 0 3 10 21

<h3>What is Linear Equation?</h3>

A linear equation is an algebraic equation of the form y=mx+b. involving only a constant and a first-order (linear) term, where m is the slope and b is the y-intercept.

Given function is:

y= $2x^{2} +x$

For finding the solution of above expression, take value of x and solve for y.

If x=0

y= 2(0)+0

y=0

If x=1,

y= $2(1)^{2} +1= 3$

If x=2

y= $2(2)^{2} +2=10$

If x=3

y= $2(3)^{2} +3=21$

The required table is:

x: 0 1 2 3

y: 0 3 10 21
