Factor x^4-y^4: (x²+y²)(x²-y²)
further factor: (x²+y²)(x+y)(x-y)
so the dimensions are (x²+y²)(length), (x+y) (width), and (x-y) (height)
Cos (A-B) - cos (A+B)
= (cosAcosB +sinAsinB) - (cosAcosB - sinAsinB)
=2sinAsinB
Ans: 4
Answer:
Option 2. h = E/mg.
Step-by-step explanation:
E= mgh
mgh = E
Divide both sides by mg:
mgh / mg = E / mg
h = E/mg.
Answer:
(x+12)(x-12)
Step-by-step explanation:
6x+2+6x<14
add 6x+6x
12x+2<14
subtract 2 from both sides
12x<12
divide by 12
x<1
