Answer:
420.00
Explanation:
Gross amount = Amount with tax
Net amount = Amount without tax
Gross amount = Net amount + 20% × Net amount
(1 + 20%) × Net amount
(1 + 20%) × 350
(100% + 20%) × 350
120% × 350
120/100 × 350
1.2 × 350 = 420
Added tax = Gross amount - Net amount
= 420 - 350 = 70
Answer:
El otro polinomio es:
2x² + 4xy -3x - y²
Explanation:
(3x - 4x² + y²) + a = -2x² + 4xy
a = -2x² + 4xy - (3x - 4x² + y²)
a = -2x² + 4xy - 3x + 4x² - y²
a = -2x² + 4x² + 4xy - 3x - y²
a = 2x² + 4xy - 3x - y²
