I'm pretty sure the simplified answer of (4x^3y^-5)^4 would be 256x^12/y^20 (this is a fraction)
Hope this helps :)
E. 8x+7(325)=15(325)
It would include the 8 hrs. of x miles per hour and the 7 hrs. of 325 miles per hour, giving the total miles. Then, as you eliminate, you can find out what (x) is.
Answer:
2x little 2on top
Step-by-step explanation:
Answer:
y = 15
Step-by-step explanation:
Given: y varies directly with x, x=4 when y=20
To find: y when x = 3
Solution:
As y varies directly as x, it means that as x increases, y also increases by the same factor.
As y varies directly with x,

Here, k is a constant
As x = 4 when y = 20,

Put x = 3

Answer:
length is 5
width is 4
