Note:
equals: =
minus: -
q is equal to f minus 3

Answer:
108
Step-by-step explanation:
Because the area formula is a*b and 12*9 is 180
So the answer is 180 which is A
I hope this helps :)
<span>Let the wall's length be y. So the fence parallel is also y.
We form the equation;
2x + y = 240
Now the area A is x*y, which is given as 5500.
We have 2 equations with 2 variables. Solve them and get the answer.
xy = 5500
2x + y = 240
Y = 5500/x
2x + (5500/x) = 240
2x^2 - 240x + 5500 = 0
x^2 - 120x + 2750 = 0
Work out the value(s) of x from above. </span>
Any number but 0 is compatible because you can add any number to 428.
