Subtract these polynomials and simplify. enter your response in standard form. (2 − 4x9 + 3x3) − (7x + x3 − 6 + 12x4)

 2 - 4x⁹ + 3x³ - (7x + x³ - 6 + 12x⁴)

= 2 - 4x⁹ + 3x³ - 7x - x³ + 6 - 12x⁴

= (2 + 6) + (-4x⁹) + (3x³ - x³) + (-7x) + (-12x⁴)      grouped like terms

=     8       - 4x⁹          +2x³       -7x       -12x⁴      added like terms

= - 4x⁹  - 12x⁴ + 2x³  - 7x + 8             standard form

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

$25

step-by-step explanation:

25 - 4.50 = 20.5

20.5 / 2 = 10.25

10.25 + 10 = 20.25

20.25 - 12.50 = 7.75

therefore the answer is $25 as shown as the first number.
