Answer:m<t =16
Step-by-step explanation:
2x^2+17x-21
(7y+2y2−7)−(3−4y)
=7y+4y+2y2−7−3
=11y−2y2−10
Hope this helps
Answer:
x=8
Step-by-step explanation:
13=x+5
8=x
Answer:
x = 8
Step-by-step explanation:

x + 5 = 13
So now we have to do the inverse operations thingy:
13 - 5 = 8
So x = 8
tell me if this is wrong so I can fix it
