$29.92

Step-by-step explanation:

Step one:

given data

The bill for dinner totaled $74.80

Then the tip is 20%

Required

The amount paid by each person after the tip was added to the cost of the dinner

Step two:'

the amount of the tip is

=20/100*74.80

= 0.2*74.80

=$14.96

=$89.76

The number of persons including the celebrant is = 3

so each person will pay

=89.76/3

- 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

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !
