X-24-8x - 2y=
combine like terms

-9x-2y-24

Step-by-step explanation:

-x-24-8x-2y

To combine like terms, the only ones you can combine would be the -x and -8x (due to both have the exponent of 'x')

-x= -1x, so -x-8x = -9x

-9x-2y-24 would be your answer since nothing else has like terms.

i believe the answer is 68cm

step-by-step explanation:

i just took 34 x 2 because the space between v and y is the same as y to k.

it would open into a square depending on the type of envelope i’m not sure about the second part
