Answer:
More than one independent variable being tested.
Step-by-step explanation:
If a student wants to figure out if ONLY salt affects the growth of seeds, the student shouldn't change the amount of sunlight being received.
First I'd expand the brackets so that you can re-simplify the values, so:
(2x + 3)(3x + 4)
6x^2 + 9x + 8x + 12
6x^2 + 17x + 12
The answer A. 2x(3x + 4) + 3(3x + 4) can be simplified the same way, with 6x^2 + 8x + 9x + 12, and so the answer is A. I hope this helps!
If both pieces of metal are made of the same material the ratio of the mass and volume will be the same. here the symbol M stands for the mass of the object, and V the volume. Density has the units of mass divided by volume such as grams per centimeters cube (g/cm3) or kilograms per liter (kg/l).
This is the process of completing the square.
Keep this equation in mind:

Basically, to make this a perfect square trinomial, you take half of b and square that value. This will make it so you can compress the left side of the equation into

depending on the sign in the middle of the original equation.
