So it would be
40-.07(40)=b
B=37.2 dollars
5/11 in decimal form is .45

=
444
aka
d
The area of a paralellogram is bh
each dimention is multiplied by n
b turns to bn
h turns to hn
bh turns to (bn)(hn) or bnhn or bhn²
expression is bhnn or bhn² or bhn^2 (depends if the program will let you enter the exponent)
