Answer: -3x³ +2x² - x + 4

<u>Step-by-step explanation:</u>

Q(x) = -x³ + x² - x + 4
P(x) = 2x - 1
-x² * P(x) = -x²(2x - 1) = -2x³ + x²

Q(x) - x² * P(x)

= (-x³ + x² - x + 4) + (-2x³ + x²)

= -3x³ +2x² - x + 4

Answer:

c. -3x^3 + 2x^2 − x + 4

Step-by-step explanation:

given

P(x) = 2x -1

Q(x) = -x^3 + x^2 - x + 4

Q(x) -x^2 * P(x)

= -x^3 + x^2 - x + 4 - x^2*(2x - 1)

= -x^3 + x^2 - x + 4 - 2x^3 +x^2

= -3x^3 + 2x^2 - x + 4

ans is C

What is the measure of angle A?

I am Lyosha [343]

First you have to find the angle B (check attachment)

$B = 180^{\circ} - 137^{\circ} = 43^{\circ}\\$

Then you can find the last angle inside the triangle, which I'll call C

$C = 180^{\circ} - 102^{\circ} - 43^{\circ} = 35^{\circ}$

Now you can find angle A

$A = 180^{\circ} - C = 180^{\circ} - 35^{\circ} = 145^{\circ}$
