Question

B.Perform the indicated operations on the given algebraic expressions.
ADDITION
(3x - 3y) + (4x + 2y) SUBTRACTION
(2x + 4y – 3z) – (-3x + 2y + z)
(7a – 6b) – (2a – 3b + 2c)
MULTIPLICATION
(4x + 4y) (5x – 2y)

Answer 1

Answer:

7x-y

5x+2y-4z

5a-3b-2c

20x²+12xy-8y²

Step-by-step explanation:

(3x-3y)+(4x+2y) = 3x+4x-3y+2y= 7x-y

(2x+4y-3z)-(-3x+2y+z) = 2x+3x+4y-2y-3z-z = 5x+2y-4z

(7a-6b)-(2a-3b+2c)=7a-2a-6b+3b-2c= 5a-3b-2c

(4x+4y)(5x-2y) = 20x²+20xy-8xy-8y²= 20x²+12xy-8y²

Answer 2

Answer:

3x+4x-3y+2y=7x-y

Step-by-step explanation:

(2x+4y-3z)-(-3x+2y+1z)

2x+4y-3z+3x-2y-1z

2x+3x+4y-2y-3z-1z

5x+2y-2z
