The smallest integer that can be added to -2m3-m+m2+1 to make it completely divisible by m+1 is

-5

Step-by-step explanation:

By synthetic division, polynomial long division or evaluating the function at x=-1, you find the remainder from division by m+1 to be 5. In order to make the remainder be zero, -5 must be added to the the expression.

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

24

step-by-step explanation:

the graph shows 30% of students walk. 80 students were questioned, so the number that said they walk is

30% × 80 = 0.30 × 80 = 24
