(3m2+4n)3
Square Metre ...... eg 3m2 = 3 square metres
I assume you mean 3 square meters? If so it is = to 32.29 sq. ft.
You can take 3m out of both of them, leaving 6m^2 + 3m + 4 over m

MX 175 F 1979 = Start Engine#: 3M2-000101 MX 175 G 1980 = Start Engine#: 3M2-100101
To solve this, you find out what 3m2= (3 meters squared). 3m2= 9, and 4m2= 16.
It is -3

(3m2+4n)3
Square Metre ...... eg 3m2 = 3 square metres
I assume you mean 3 square meters? If so it is = to 32.29 sq. ft.
Assuming the missing symbols are pluses, that factors to 3(m + 3)(m + 7)
To calculate the area, we divide the force (1500 N) by the pressure (500 Pa) to get an area of 3 square meters. For the second part, if we double the area to 6 square meters and keep the force constant at 1500 N, the pressure would be halved to 250 Pa over the new larger area.
9m² or 9 square meters or 9 meters squared
Pressure is equal to force divided by area (F/A). You already know that the area is 3m2, so now you just have to find out the force of the water on the base of the tank. First of all, you need to work out how much water there is, so you can determine it's mass and from this how heavy it is in the tank (this is the force - the waters own weight). The volume of the water tank is Area times height (V = A * h). So the volume of this water tank is 3*2 = 6m3. Now, every m3 of water has a mass of 1 kg, so in this tank we have 6 * 1kg = 6kg of water. The weihgt of the water (force towards ground) is its mass times the acceleration due to gravity (what's holding your feet to the ground), as given by Newton's second law. So the water's weight (or force on the bottom of the tank) is 6 * 9.8 (acceleration due to gravity = 9.8 ms2) = 58.8 Newtons. And now we work out pressure... Pressure = force/area = 58.8 N/3m2 = 19.6 N/m2 Hope that helps
