Amap is draw so that every 1 inch on the map represents 50 actual miles. the table below can be used to record the actual distances between towns on the map

200

Step-by-step explanation:

Since we know that every inch on the map is equal to 50 miles, and the table doesnt give us any information other than that you can just add

50=1 inch

100=2 inches

150 =3 inches

200= 4 inches

so 4 inches on the map is 200 miles..

- 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

72 is the answer to this problem
