2. If you had an equation like 7x+4 + 3x +2 you would separate like terms like this. 7x+3x + 4+2 add these together to get 10x + 6 to get your answer

3. A coefficient is the number before the variable for example in 5x the 5 is a coefficient and x Is variable. If you had an equation like 5x+3-2x. 5 and 2 are coefficients abut 3 is a constant because it doesn't have a variable behind it.

4. Distributive Property is when you take an equation like 2(1+2) and solve it by distributing 2 like this 2(1+2) and

5. Exponents are the shortened expression of a repeated equation for example if you had. 2x2x2x2x2x2x2x2 an exponent of it would be 2^8

6. To multiplying fractions all you have to do is multiply the numerators together and then multiply the denominators together like this. 2/3 x 4/5 = 8/15

7. The Cartesian is a type of graph were you mark a point on a graph by using the x and y coordinates, like this. = 5,6

8. The line that goes up or down (horizontal on a graph

9. Integers are whole numbers (numbers with no fraction 1,2,3,4,etc.) but also include negative numbers.

10. When you are multiplying fractions the “saying” you would use to describe it is just do it fro example if you had. 2 3 3 4 X You would just do 2x3 and 3x4 to get 6/12

11. In an equation like 3x + 2 + 3x = 4x – 2 all of the numbers with a variable at the end are like terms and all of the numbers without a variable are like terms. If I was to group them it would be 3x, 3x, 4x and 2,-2

12. Modeling polynomials is just drawing a picture to represent the numbers -1 Tile +1 tile +X tile -X tile + x^2- x^2

13. The numerator is the top number in a fraction for example: 2/3. when you multiply fraction you just and the two numerators together as well as the denominators

14. The order at which you do an equation “BEDMAS.” In an equation you would do brackets than exponents than divide and or multiplication and adding or subtraction

15. When you have an equation written like this (3^2)^3 this written out would be. (3^2)(3^2)(3^2) This law means you times the two powers together for example (3^2)^3 would = 3^6

16. The answer you get when you divide two numbers together for example in 8/4 = 2. 2 is the quotient 8 is the dividend and 4 is the divisor.

17. A rational number is a number you can right as a fraction. Numbers like 5,1.75 and.001 can be written as fractions 5/1 7/4 and 1/1000 so they are all rational numbers.

18. We learned how to calculate the surface area of an 2 objects but together like this you would have to ad up the two surface areas by doing SA= 2(l X w + w X h + hXl) the subtract the are off the base of the smallest prism the add up the two areas and subtract the base twice

19. A trinomial is a polynomial with three terms so 3x 2 − 3y 2 + 2 is a trinomial but 5 5 + 9x 5 wouldn't it would be a binomial

20. Unlike like terms unlike terms are number that don’t match like 2x and 3 these are unlike terms because you cant mix these together you cant have 3+2x you have to do other steps to find the answer you can just add them together

21. A variable is the letter in an equation like in 2x + 3 – 4 x behind two is a variable. Variable can also be by themselves like in an equation like 2 + x – 2 X is also a variable

22. Whole numbers are simple plain numbers like 1,2,3,4 but unlike integers they do not include negative numbers

23. The line that runs horizontally through a graph

24. The line that runs vertically through the graph

25. Zero pairs is when you have two numbers that cancel each other out for example +1 and -1 make a zero pair. If you had the equation 5x + 3 – 5x the to 5x would cancel each other out because they one is a negative and one is a positive
