Answer:
-12w^3+32w^2-136w+80
Step-by-step explanation:
4(2-3w)(w^2-2w+10)
multiply first two:
(8-12w)(w^2-2w+10)
multiply:
8w^2-16w+80-12w^3+24w^2-120w
simplify:
-12w^3+32w^2-136w+80
Answer:
$180
Step-by-step explanation:
Since the cost of the telescope with the 30% discount is $126 then $126 is 70% of the original price. Remember 100-30=70. To find the original price set up a proportion with these values:

Solve for the original price by cross multiplying numerator with denominator.
x(70) = 126(100)
70x = 12600
x= $180
