2 equations, 2 unknowns. Call height H and base B.
From the first sentence:
HB = 216
From the second sentence:
H = ⅔ B
Plug the second into the first and solve for B:
(⅔ B)B = 216
B^2 = 324
B = 18
Plug that back into either of the original 2 equations and solve for H:
H(18) = 216
H = 12
Count the difference of the x values between the two points (the run of the slope) and the difference of the y values between the two points (the rise of the slope). That would get you the rate of change, or slope, of the line.
Let the unknown integer be x
x*2+19=-44
x=-44-19/2
x=63/2
x=31.5
The bat costs $50 but on clearance, it is an additional 30% off.
50 - (50x.3) = x
50 - 15 = x
35 = x
The sale price of the bat is $35.
The answer is A.
When simplifying radicals, you can factor out anything that is a root. In this case we have a 4th root. We can break 144 to 16*9. By doing this, we can pull out 16 which has the 4th root 2 (2*2*2*2=16). Next, a^12 has the 4th root a^3. We can't do anything with the b^3 so it stays inside the root with the 9.
