Answer:
You can go for 1x9, 2x8, 3x7, 4x6, 5x5.
5x5 is the best as it builds a square, which maximizes space.
20*2.50 = $50.
Step-by-step explanation:
We need to find an expression for
.
We can solve it as follows.
We know that,

So,

or

Hence, this is the required solution.
Answer:
a3= -343
divade both side by 3 to make a the subject
a3/3= -343/3
a = -114.3
