(7x^2-3x)+4x^2
7x^2+4x^2-3x
11x^2-3x
Answer: 11x^2-3x.
You just combine like terms.
That would be written 5s+10
First, factor out h so the equation can be h(b+r)=25 then divide by b+r so h= 25/b+r
Answer:
35x^2 - 112x - 364
it's probably wrong since I've only expanded the brackets
The value of this is -1 so the answer is B.
HOPE THIS HELPS!
HAVE A GR8 DAY;-)
