Answer:
12 shirts
Step-by-step explanation:
find the price of 2 shirts:
(1/2 x 34.98)+34.98=52.47
for every 2 shirts she buys, she pays $52.47
314.82/52.47=6
she bought 6 pairs= 12 shirts
F(a)=-2a^2 - 5a^4
if a=-3
f(-3)=-2(-3)^2 - 5(-3)^4
=(-2*9) - (5*81)
=-18 - 405
=423
Step-by-step explanation:
6 times7-3^2 times 9+4^3=
(6*(7-3^2))*(9+4^3) =
(6(7-9)) *(9+64) =
(6*-2) (73) =
-12*73
