For what value of k, is the polynomial p(x)= 3x4 – 9x3 + x2 - 15x + k completely divisible by 3x2 - 5

k = -10

Step-by-step explanation:

When we expand the above

When we take consider with the original expression

3y - 5 = 1

3y = 6 ⇒ y = 2

k = -5y ⇒ k = -10

answer: c

step-by-step explanation: because you don't have to draw a point of intersection. couldyou give me brainliest?

we have three similar triangles, because each has a right angle and shares an angle.   let's write the angles in order: opposite to short leg, long leg, hypotenuse.

cab similar to bad similar to cbd

or as ratios,

ca: ab: cb = ba: ad: bd = cb: bd: cd

we also know

ac = ad + cd

(ad+cd): ab: cb = ba: ad: bd = cb: bd: cd

(ad+cd)/cb=cb/cd

we have cb=6, ad=5 and seek x=cd.

we reject the negative root and conclude x=4

answer: 4
