If fi(x) = 2x3 + 5x2 – 3x + 3 and f(x) = x3 – 3x2 – 2x + 1. Find 2fı (x) + 3f(x) (A) x3 + x² - 12x + 9
(B) 3x3 - x? – 10x + 9
(C) 7x3 + x2 - 12x + 9
(D) 7x3 + x2 + 5x - 1

  q

step-by-step explanation:

each line from a vertex to the midpoint of the opposite side is called a median. the point where the medians intersect, point q, is the centroid.

the centroid of δabc is point q.

13

step-by-step explanation:

169-1=168

168-3=165

165-5=160

160-7=153

153-9=144

144-11=133

133-13=120

120-15=105

105-17=88

88-19=69

69-21=48

48-23=25

25-25=0

since it took 13times to completely subtract it hence its square root is 13

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
