Which pair shows equivalent expressions? 2x+10=-2(x-5)

-2(x+5)=2x-10

-2x-10=-2(x+5)

-2(x-5)=-2x-10

Answer: -2x-10=-2(x+5)

-2x-10

Taking out common factor -2

= -2( x + 5 )

-2x-10

Taking out common factor -2

= -2( x + 5 )

Answer:

Answer: -2x-10=-2(x+5)

-2x-10

Taking out common factor -2

What is the measure in degrees of 8x if one angle is already 7x and 44.4 degrees?

7x+8x+44.4=180

15x=44.4=180

15x=135.6

x=9.04°

so 8x=72.32° and the 7x is 63.28°

15x=44.4=180

15x=135.6

x=9.04°

so 8x=72.32° and the 7x is 63.28°
