Answer 1

Answer:

hey! good afternoon

Step-by-step explanation:

(7x-3)-(3x-4)

=7x-3-3x+4

=4x+1

if 2x+4 is cut we have

(4x+1)-(2x+4)

4x+1-2x-4

2x-3

this is your answer ☺

Answer 2

Step-by-step explanation:

Data:

Data: Wire is : (7x-3) m long

Data: Wire is : (7x-3) m longWire cut : (3x-4) m

Data: Wire is : (7x-3) m longWire cut : (3x-4) m a) How much wire was left?

Data: Wire is : (7x-3) m longWire cut : (3x-4) m a) How much wire was left?(7x-3) - (3x-4)

7x -3 -3x -4 (OPENING THE BRACKET)

7x -3x -3 -4 ( LIKE TERMS TOGETHER)

4x - 7. ( SOLVING THEM)

4x -7 wire was left.

B. IF (2x + 4) m is cut out more, how much wire will be left then?

REMAINING WIRE : 4x - 7

Wire cut out of remaining : ( 2x + 4)

4x -7 - ( 2x + 4 )

4x -7 - 2x + 4

4x - 2x -7 + 4

2x - 3

2x - 3 wire was left after being cut by remaining wire

please mark me brainliest. it took me a lot of time
