Just one
11x+25=7x+15
11x - 7x = 15 -25
4x = -10
x = -10/4
x = -5/2
Answer:
almost nobody here understands your language sorry
Put 34 in place of the z. The problem is basically asking what equation can you do to get -24?
2 + 8 - 34 = -24
Answer:
40 + 4x
Step-by-step explanation:
formula for perimeter:
( length * 2 )+(width * 2)
you know that the length and width will be increased by the same number so you can call that X.
((length + x)*2) + ((width + x) * 2)
then substitute length and width
((15+x)*2) + ((5+x)*2))
you can simplify this a bit more
30 + 2x + 10 + 2x
40 +4x
Goodluck with your schoolwork/homework!
