Ronny Dorge: These are really easy questions. I will tell you how tofind the answers and then you'll be able to do them in a snap. Just pay attention in class nex time!!!9. D (because a term is a group of numbers and variables multiplied together, (y - x) is not, it is subtraction!!!)10. B (same reason as above)11. A (just eliminate anything with x, A has x^2 which different!)12. C (just eliminate anything that has x^2)13. D (coefficients are fancy words for the number right in from of the varibles(letters). Isnt that easy?)14. D (you know how to do that now)15. D (just add the coefficients(numbers) of terms(each cluster or group of numbers and variables) with the same variables(letters), -2x and 8x go together, and the rest are seperate)16. You know how to do it now so try this one yourself17. When ther are brackets, multiply the outside number with EVERY TERM in the inside. If there is no numbers outside, pretend there is a 1. For this questio! n: for the first bracket, just take it off, and for the second, multiply every term inside (4x and 4z) with -2. So you get -8x - 8z for the second part. Then add like terms and you're done!!18. Use the method I told you in question 17. This is what you should get:3 + {4y + 2(x^2 + y )} + x^2= 3 + {4y + 2x^2 + 2y} + x^2= 3 + 4y + 2x^2 + 2y + x^2= 3 + 4y + 2y + 2x^2 + x^2= 3 + 6y + 3x^2hope this helps you for homework and tests in the future. If you dont get a concept, nag your teacher to explain it properly until you get it! If you get it but you are just lazy to do your homework, I dont understand why, it literally takes 5 minutes to do this....Show more
Barton Morfee: i havent performed maths for a 300 and sixty 5 days because of the fact i finished my GCSE's yet i did get an A im somewhat rusty so i cant help with selection one million yet 2 ounds like its simultaneous equations...i've got been given... (5x + 3) = (3x +9) you need to multiply the two equations so as! which you have equivalent style of x's in the two... (5x + 3)! x 3 = (15x + 9) (3x + 9) x 5 = (15x + 40 5) subtract the 2nd equation from the 1st... (15x + 9) - (15x + 40 5) = -36 ... because of the fact the x's cancel one yet another out as a result you purely do 9 - 40 5 so x = -36 (notice the respond is detrimental, i havent basically made a typing blunders) desire its actual lol, and desire it helps...Show more
