Answer:
40x^2-68x+41
Step-by-step explanation:
Multiply both expressions
(-2x+5)^2= 4x^2-20x+25
(6x-4)^2=36x^2-48x+16
Then add
Use multiplication table if you have difficulty with multiplying
Ex
-2x 5
-2x 4x^2 -10x
5 -10x 25
Then add them all to get the full expression
he paid = 4*10 = $40
48 eggs = $40
so, waste money would be 6/48 * 100 = 12.5%
