Henry and Samual volunteer at the daycare center and he worked three hours for every two hours Samual works if the two boys together work 20 hours one month how many hours does henry work

Answers

Sorry if this isn't clear It's a ratio question. Henry does 3 hrs for every one of Samuel's 2hrs, the ratio is 3:2 The total number of parts is 5 and to work out one part, divide 20 by 5 =4 So if Henry does 3hrs for Sam's 2hrs, he does 4 x 3 to get his part of the total 20hrs 4 x 3 = 12 And Sam does 2hrs, he does 4 x 2 = 8 So Henry does 12hrs a month

12 divided by the sum of h and 2

Write it in algebraic expression

Answers

12 divided by the sum of h and 2....

12 / (h + 2)

Since h and 2 together is a sum, and sum is what you get when you add two or more number/variables, add h and 2 for the expression h+2.
Since 12 is being divided by (h + 2), put the 12 above the h+2. This gives you the following expression:
$(12)/(h+2)$

F(x)=x^3-3x^2-x+3

Factor each by grouping

Answers

Answer:

F(x) = (x - 3) (x + 1) (x - 1)

Step-by-step explanation:

F(x)=x³-3x²-x+3 = x² (x - 3) - (x - 3) = (x - 3) (x² - 1) = (x - 3) (x + 1) (x - 1)
