Solve each equation for the indicated variable: u=p-2x+ay, solve for a

Start with

Move all terms not involving to the left, i.e. add to both sides:

Divide both sides by . To do so, we must assume

And we have solved the equation for a:

109 is the nearest whole number/final answer! : )

30 units^2

step-by-step explanation:

area is l × w

the length is 3

and the width is 10

3 × 10= 30 units squared
