Step-by-step explanation:
= (3x² + x + 8) + (x² - 9)
= (3 + 1)x² + x + (8 - 9)
= 4x² + x - 1
Answer:
length of box = 56cm
breadth = 0.4m = 40cm
height = o.25m = 25cm
Volume of Box = Volume of soap × n
n = number of soaps.
LBH = lbh × n
56 × 40 × 25 = 7 × 5 × 2.5 × n
n = 56×40×25/35×2.5
n = 56000/87.5
n = 640
so, 640 soaps can be placed in the box.
To be honest I’m not sure but I believe it’s -7 if there’s anymore information please attach it along with your question
Answer: first graph is F(x) = 0.5(x-6) (x+2)
Second graph f(x) = (x - 3) ( x + 1 )
Third graph f(x) = -2(x - 1) (x + 3 )

Answer:
1)
Step-by-step explanation:
l x w and w x h are all formula for a rectangle, not a cube.
For instance, let's take l x w. If we change the height it will definitely change the volume, but according to 2) it won't. So, 2 is wrong.
We can do the same process for 3) to show it's wrong.
So, the answer is not 2) or 3), so it must be ![\boxed{1)}](https://tex.z-dn.net/?f=%5Cboxed%7B1%29%7D)
