Answer:
The zeroes would be -3 and a double root at 5.
Step-by-step explanation:
We can find this by first expanding the function.
c(x) = (x + 3)(x - 5)^2
c(x) = (x + 3)(x - 5)(x - 5)
Then we can solve for the zeroes by setting each parenthesis equal to 0 and solving.
x + 3 = 0
x = -3
x - 5 = 0
x = 5
x - 5 = 0
x = 5
Answer:
x = 2
Step-by-step explanation:
Express the ratio in fractional form
= 
( cross- multiply )
6x = 12 ( divide both sides by 6 )
x = 2
Answer:
525,000 LL
Step-by-step explanation:
6 x 3 = 18 (days)
150,000 x 3 = 450,000
21 - 18 = 3 so 6 * 2 = 3 ( 150,000 *(divide) 2 = 75,000)
so 450,000 + 75,000 = 525,000
Samuel needs to estimate the product of 24 x 395.
First method
We round the number to nearest tens
24 can be rounded to 20 because we have 4 on ones place
395 can be rounded to 400 because we have 5 in ones place so we add 1 with 9 and it becomes 10 . so we add 1 with 3 and got 400
20 * 400 = 8000
Second method:
We round the number to nearest hundreds place
24 have no number in hundreds place so it remains 24
395 can be rounded to 400 because we have 9 in tens place.
24 * 400 = 9600
