For the following values of a and b, find q e ℤ and r e ℤ so that a = qb + r and 0 ≤ r < i b i 1. a = 1211 and b = 5 2. a = 7521 and b = - 25 3. a = -8989 and b= 88 4. a = -4225 and b = -9

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10

step-by-step explanation:

3/6 chance

step-by-step explanation:

half of the nubers are odd numbers (1,3,5) which in that case if you would be told to simplify it would be 1/2
