Answer:
=
Step-by-step explanation:
You want to match up the sides for this one.
The first answer would be incorrect because the sides aren't the same from the bigger on to the smaller.
The second answer would be incorrect because the first one goes from the bigger figure to the smaller one but on the other side of the equal sign goes from the smaller figure to the bigger figure.
I can't see the denominators on the third one but if its:
=
then thats correct because it matches all the sides
Answer:

Step-by-step explanation:
we are given a quadratic equation
Let's assume formula of vertex form of parabola as

where vertex is (h,k)
we are given
vertex =(11,-2)
so, h=11, k=-2
now, we can plug it

now, we are given zeros at x=10 and x=12
we know that zeros will be x=10 , y is 0
so, we can plug x=10 and y=0 and solve for 'a'



now, we can plug it back
and we get

so, we get quadratic equation as

Answer:where is the question??.?
Step-by-step explanation:
Answer:
Katie made a mistake. P = (nRT)/P is the correct equation, not V = PnRT
Step-by-step explanation:
The equation for the ideal gas law is PV = nRT, where P is pressure, V is volume, n is the moles of gas, R is the gas constant, and T is the temperature, in Kelvin.
Solving for V:
PV = nRT
V = (nRT)/P
Katie did not solve the equation corretly. To move V from the left to the right side of the equation, she needed to divide both sides by P:
PV = nRT
PV/V = (nRT)/P
P = (nRT)/P is the correct equation
1: 4.5 ft by 6 ft
2: 27 sq. ft.
First, just multiply 3 and 4 by 1.5 to convert inches to feet using the scale. You end up with 3*1.5 and 4*1.5, which equals 4.5 and 6. So the dimensions are 4.5 feet by 6 feet.
Now, just multiply 4.5 by 6 to get 27 square feet.
