In the figure, the segment is parallel to one side of the triangle. The ratio of x to 16 is a.1/2
b.1
c.2
d.3

A)

Step-by-step explanation:

6/12=x/16

12x=96

x=8

6/12=8/16

simplified to 1/2

Therefore, the answer is A)

4sqrt5

step-by-step explanation:

the base has dimensions of 8 x 4, so the diagonal is 64 + 16 square rooted or 4sqrt5.

- 2 + 10x³ - 21x² + 19x - 4

step-by-step explanation:

each term in the second factor is multiplied by each term in the first factor

x²(- 2x² + 4x - 1) - 3x(- 2x² + 4x - 1) + 4(- 2x² + 4x - 1) ← distribute

= - 2 + 4x³ - x² + 6x³ - 12x² + 3x -8x² + 16x - 4

collect like terms

= - 2 + 10x³ - 21x² + 19x - 4 ← in standard form
