Calculate the product 45.67x32.58 rounded to the nearest penny
serg [7]

We assume the monetary amount is a number such that the hundredths place represents a penny. (It's not billions of dollars, for example.)

45.67×32.58 = 1,487.9286 ≈ 1,487.93

_____

Any calculator can give you the product. Most will round the number for you if you specify a 2 decimal digit display.

The thousandths digit of the product (8) is more than 4, so the hundredths digit (2) is increased by 1 (to 3) as the digits to its right are dropped.

A little help would be nice
Katena32 [7]

Answer:

13). -2x³ + x² + 1   14). x + 10y - 10z   15). -2x³ + x² + 1

Step-by-step explanation:

13). (x³ - x² + 4) - (3x³ - 2x² + 3)

= x³ - x² + 4 - 3x³ + 2x² - 3

= x³ - 3x³ - x² + 2x² - 3 + 4

= -2x³ + x² + 1

14). (3x + 4y - 3z) - (2x - 6y + 7z)

= 3x + 4y - 3z - 2x + 6y - 7z

= 3x - 2x + 4y + 6y - 3x - 7z

= x + 10y - 10z

15). (x³ - x² + 4) - (3x³ - 2x² + 3)

= x³ - x² + 4 - 3x³ + 2x² - 3

= x³ - 3x³ - x² + 2x² + 4 - 3

= -2x³ + x² + 1
