The sum of the two digits of a number is 9. if the tens digit is one-half the units digit, what is the number? let t = the tens digit, u = the units digit, and t + u = 9. which of the following equations would complete the system? t = 1/2u u = 1/2t t - u = 1/2

Requested number is 36

Step-by-step explanation:

The first equation is as given t + u = 9

The second equation is t = (1/2)u => u = 2t

When we replace this in first equation we get:

t + 2t = 9  => 3t = 9  =>   t = 9/3 = 3

When we replace again in the

u = 2 t = 2 · 3 = 6

The requested number is  36

- 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
