Answer:x^2-y^2
Step-by-step explanation:
(x+y)(x-y) = x^2 -xy +xy -y^2 so it becomes x^2-y^2
You first subtract and a e. E see where that gets you subtract or add the first number
Answer:
96 square meters
Step-by-step explanation:
Figuring out the side length of a cube from its volume is fairly simple. Using the cubic root we are able to deduce that the side length is 4 meters.
We then find the area of one face which is 4 * 4 = 16 square meters.
We must then multiply this by the amount of sides on our cube which is 6.
16 * 6 = 96 square meters.
If the 5 of them weigh 1/4 of a ton
then 1 of them weigh x
5/1 = 1/4//x Do you see what happens? Just by writing down the givens you get a proportion. It will work better for you if you change the 1/4 to 0.25
5/1 = 0.25/x Now it looks like an ordinary proportion. Cross multiply
5x = 0.25*1 divide by 5
x = 0.25/5
x = 0.05 tons. We better change this to pounds.
1 ton = 2000 pounds
0.05 ton = x
1/0.05 = 2000/x Cross multiply
x = 2000 * 0.05
x = 100 pounds.
Answer:
<h2>Time is the independent variable and Height of the Grass is the dependent variable.</h2>
Step-by-step explanation:
The graph is about the height of the grass thourgh time, that means Brady is analysing how long it takes to the grass to grow.
It's important to know that time is a variable which doesn't depends on any other variabel, that is, it's an independent variable all the time.
Therefore, Time is the independent variable and Height of the Grass is the dependent variable.
This is just simple deduction, because the grass grows through time, it doesn't happen in the opposite way, time doesn't change accoring to the height of the grass.
