Question

Find which is greater {(-3)-4}x(-5) or (-3)-4x(-5)

Answer 1

{(-3)-4}x(-5) = 35x

(-3)-4x(-5)=15 +20x

try diff value for x we always find that 35x is greater than15 +20x.

SO {(-3)-4}x(-5) IS GREATER

     

Answer 2

Answer:

[(-3)-4]×(-5) > [(-3)-4×(-5)]

Step-by-step explanation:

i ) [(-3)-4]×(-5)

= (-7)×(-5)

= 35 ----( a )

ii ) (-3) - 4×(-5)

= -3 + 20

= 17 --- ( b )

From ( a ) and ( b ) ,

35 > 17

Therefore ,

[(-3)-4]×(-5) > [(-3)-4×(-5)]
