Can anyone tell me what the answer to this problem is and the explination?

The figure shown above is triangle. The area of the triangle is a= 1/2base times height.

Base  is 10 .  The height is 6.

A= 1/2bh

A= 1/2*10*6

A= 1/2*60

A= 30

Or you can find the area of the triangle separately and add them up.

First triangle :

The half of the base is 10/2= 5

B= 5  H= 6

A= 1/2*6*5

A=  15

Second triangle :

b= 5

h= 6

a= 1/2*5*6

a= 15

Add up them both areas 15+15= 30

your welcome haha, this is the best place to find answers

- 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
