Question 509565: Ok my teacher explained this to us, but she didn't explain the problems like the one in the following. Can you please help me solve it but, ill show you how i think its done too:
The instructions are: Use the distributive property to write each
expression as an equivalent algebraic expression.
(9-h)5 = 5(9)+ 5(h)
45+5h

Question 515015: How do you foil in reverse? When two numbers multipled together equal the last number of the equation and then the same two numbers must add up to te number in the middle of the equation. Is there a trick to solving these? Example:29y+41+50

Question 519311: Instructions are to simplify each expression and tell which property you used:
Ex. 6 x 23, teacher did example as =6(20+3) and indicates "distribute".
Ex. 13 x 12, teacher did example as =12 x 13 and indicates "commutative".
Is there any particular reason she didn't do the second example as =13(10+2) (distributive) or the first example as =23 x 6 (commutative)?
Can you just chose either randomly depending on what's convenient for mental math or is there an absolute answer?

Question 520539: I am really stuggling in Elementary and Intermediate Algebra. Math does not come very easily for me. I am stuck on equations and the distributive problems. I just dont understand why a problem like this.......
 . I dont understand why the negative two that is in parenethis will change to positve. I just dont get understand the concept. Do you have any recommendations on how to apply this information and to help me understand math a little better. I am tring to learn as I go and I am not having much luck. Please if you have any information I would greatly appreciate it.
