Answer:
$126
Step-by-step explanation:
90 x 1.40 = $126 = 40% profit of cost.
126 / 0.90 = $140 original price before 10%
= $126 discounted price
proof 140 x 0.10 = $14
140 - 14 = $126 the price wanted.
Answer:
x^4 + 7x^3 + 12x^2
Simplifying
x4 + 7x3 + 12x2
Reorder the terms:
12x2 + 7x3 + x4
Factor out the Greatest Common Factor (GCF), 'x2'.
x2(12 + 7x + x2)
Factor a trinomial.
x2((4 + x)(3 + x))
Final result:
x2(4 + x)(3 + x)
