9. Use synthetic division to completely factor y = y3 - 4x2 - 9x + 36 by x + 3. y = (x + 3)(x - 4)(x - 3)
y = (x + 3)(x + 4)(x - 3)
y = (x + 3)(x + 4) (x + 3)
y = (x + 3)(x - 4)(x + 3)

∠acb = 8°

step-by-step explanation:

∠xba lies on the circle and is half the measure of the intercepted arc ax

hence

measure of arc ax = 2 × 42° = 84°

∠acb is outside the circle and is

∠acb = (arcab - arcax ), hence

∠acb = 0.5 (100 - 84) = 0.5 × 16° = 8°

question:

could we have options?

step-by-step explanation:

ok so im not 100% sure but you would start by adding 5.1t and 1.9t beacuse they have the same variable. that is 7t.   then add -3.6 + 1.2 which is -2.4

so then keep that as -2.4 + 7t. i apologize if this is incorrect. best luck on your test < 3
