During 3 days joy the cat was catching mice .Each day joy caught 3 mice more than the previous day .On the third day joy caught twice as many mice as on the first day . In total how many mice did joy catch during the three days

27

Step-by-step explanation:

Given

During 3 days the cat was catching mice

Suppose the first-day joy caught x mice

So, on the second day, it is x+3

on the third day, joy catches twice as many mice as on the first day i.e. 2x

or we can also write, no of mice caught on the second day plus 3 is equal to no of mouse caught on the third day

In three day time, it is

-2 is the right

answer is 8x+24

area of vanessa's patio = length × width

given, length = (3x² + 5x + 10)

width = (x² - 3x - 1)

area of vanessa's patio = (3x² + 5x + 10)(x² - 3x - 1)

= 3x²(x² - 3x - 1) + 5x(x² - 3x - 1) + 10(x² - 3x - 1)

= 3x⁴ - 9x³ - 3x² + 5x³ - 15x² - 5x + 10x² - 30x - 10

= 3x⁴ - 4x³ - 8x² - 35x - 10

hence, expression of vanessa's patio = (3x⁴ - 4x³ - 8x² - 35x - 10)
