Answer:
2 (length +breadth)
Step-by-step explanation:
2(2x+3) (x+1)
Multiply two on both sides and solve it
Answer:
6
Step-by-step explanation: You can set up the equation:
=
You square both sides to cancel out the squares which leaves you with
= n - 4. Then you just solve as normal which ends you up with an answer of 6. You can check this by plugging 6 back into the equation and see that you end up with
on both sides.
(3x+4) (x+2)
This gives you 3x^2 + 6x + 4x + 8
Which simplifies to 3x^2 + 10x + 8
