Question

Simplify the following expression.
3y-2x+z-2x+3(x+y)
A. -x+4y+z
B. -x+6y+z
C. x+4y+z
D. 3x+4y+z

Answer 1

i think its c.

Answer 2

First expand 3(x + y) to give
3(x + y) = 3x + 3y
Then group the terms in x and the terms in y to give
3y + 3y + 3x - 2x -2x + z
Can you find the answer now by adding the terms in x and adding the terms in y?

Answer 3

no so it will be B.

Answer 4

6y-x+z
i feel like i got that wrong

Answer 5

NO CUZ LIKE THAT GURL SAID 3Y+3Y= WOULD EQUAL 6Y

Answer 6

@brittbrat213 You got it right. When you rearrange the terms in your answer you get B.

Answer 7

oh okay i get it now will it be the same when it uses exponents? or will it be different

Answer 8

It would be best if you give a question with exponents. You must group terms with the same variable and the same exponent.

Answer 9

i have trouble on this 2 sometimes dont feel bad

Answer 10

Simplify the expression.
2x^2+8+3x^2+4x-10
A. 5x^2+4x-2
B. 2x^2+x-10
C. 2x^2-x+10
D. 5x^2+7x-11

Answer 11

i think B. or D.

Answer 12

\[2x ^{2}+3x ^{2}+4x+8-10=?x ^{2}+4x-2\]
Can you find the coefficient of x^2 ?

Answer 13

is it 5?

Answer 14

Yes, the coefficient of x^2 is 5. So the correct choice is A :)

Answer 15

can you help me with 3 more questions? :s

Answer 16

Best if you post them as new questions so others can help too :)
