that is the square base+4 triangles
that is
side^2+4(1/2bh)
where b=side=14in
and h=height=13in

surface area=14^2+4(1/2)(14)(13)
SA=196+(2)(182)
SA=196+364

If Peter withdrew $47.27 from the bank and deposited $598, how would his bank account change? (Indicate how much his account wou

fredd [130]

Answer:

Since we do not know the balance we should start with, a general answer:

$b_{new} = b_{old} + \sum_{i} d_{i} - \sum_{j} w_{j} \\$

598 - 47,27 = 550,73, assuming b_old was 0$ for your example

Step-by-step explanation:

b stands for balance (old - before any deposits or withdrawals, new after all done)

d for deposits

w for withdrawals
