The name for facts in subtraction problems: Fact Family is a group of math facts that uses the same numbers, for addition, and subtraction.
Answer: =====> I believe is, Subtraction Fact Strategies, or Fact Families.
1. ). Strategy: ===> Think Addition:
1.). Subtraction Description ====> Using the known addition fact to solve the subtraction problem. Ex. 13-5, think what goes with 5 to make 13?
2.). Strategy: ===> Fact Families
2.). Subtraction Description ====> Think of the fact family to recall the missing number.
3.). Strategy ===> Build Up Through
3.). Subtraction Description ===> Ten
Used when either the subtrahend or minuend is 8 or 9. Ex: 14-9: start with 9 and work up through 10: 9 and 1 is 10 and 4 more makes 5.
4.). Strategy ==> Back Down Through Ten
4.). Subtraction Description: ==> Working backward with 10 as a “bridge”. Ex. 15-6, Take 5 away from 15 to get to ten. Then take one more away, leaving 9.

Answer: A. 51
Step-by-step explanation:
Just count all the gum balls in the machine to get the TOTAL possible outcome! (18 green + 11 white + 15 purple + 7 blue gum balls= 51)
When multiplying two binomials (expressions with two terms), you can use the FOIL method. Our two binomials are (3x - 7) and (3x - 5).
See picture. FOIL is an acronym for
First,
Outside
, Inside
, Last. Add the products of the first, outside, inside, and last terms of each binomial to multiply binomials.
For this problem:1) Multiply the
first terms, 3x and 3x.

2) Multiply the
outside terms:

3) Multiply the
inside terms:

4) Multiply the
last terms:

5) Add all the products from FOILing together:
