which expression is equivalent to: (7xy-3xz+yz)+(3xy-5xz+4yz)?

10xy+8xz+5yz
10xy-8xz+5yz
10xy-2xz+5yz
10xy+2xz-5yz

10xy-8xz+5yz

show work?

To find the equivalent expression, we can simply add the like terms:

(7xy-3xz+yz) + (3xy-5xz+4yz)

Group the like terms together:

(7xy + 3xy) + (-3xz - 5xz) + (yz + 4yz)

Combine the like terms:

10xy - 8xz + 5yz

Therefore, the equivalent expression is 10xy - 8xz + 5yz.

which expression is equivalent to: -4(2x+3)+5?

-8x+8
-8x-7
-8x+7
14x

To find the equivalent expression, we need to distribute the -4 to each term inside the parentheses and then simplify:

-4(2x+3) + 5

-4 * 2x + -4 * 3 + 5

-8x - 12 + 5

-8x - 7

Therefore, the equivalent expression is -8x - 7.

To find the equivalent expression, we need to distribute -4 to each term inside the parentheses:

-4(2x+3) + 5

= -4 * 2x + -4 * 3 + 5

= -8x - 12 + 5

Next, we can simplify by combining like terms:

= -8x - 7

Therefore, the equivalent expression is -8x - 7.

simply 1/3(9x+15)

To simplify the expression 1/3(9x+15), we need to distribute 1/3 to each term inside the parentheses:

1/3(9x+15)

= 1/3 * 9x + 1/3 * 15

= 3x + 5

Therefore, the simplified expression is 3x + 5.
