hope this helps :)
To find the dimensions you can just factor the equation...
x^2+4x-21
x^2-3x+7x-21
x(x-3)+7(x-3)
(x+7)(x-3) and this is equal to LW or WL
And note that x>3 for any possible solution.
Answer:
1. $30
2. $47.50
3. $7.20
Step-by-step explanation:
1. ( 30 + 45 + 15 ) / 3 = 30
2. ( 18 + 93 + 34 + 45 ) / 4 = 47.50
3. ( 9 + 4 + 5 + 8 + 10 ) = 7.20
