Sula's grandmother visits every fifth month. her grandfather visits every sixth month. the ladt time they both visited in the same month was january, 1995 when will they next both visit in the same month?

July 1997

Step-by-step explanation:

The LCM of 6 and 5 is 30.

30 months after Jan. 1995 is 24 months later + 6 months later.

This is 2 years later + 6 months later.

2 years later is 1997 and 6 months later is July.

Therefore, the answer is July 1997.

- 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
