Answer:
- (27n^3 - 12n - 1) over 3n
Step-by-step explanation:
Answer:
[(cosθ-1)^2]/(sinθ)^2
Step-by-step explanation:
(cotθ-cscθ)^2
(cotθ)^2-<em>2cscθcotθ</em>+<u>(cscθ)^2</u>
(cosθ/sinθ)^2-2<em>(cosθ/(sinθ)^2) +</em><u>1/(sinθ)^2</u>
All have same denominator, (sinθ)2, add/subtract
((cosθ)^2-2cosθ+1)/(sinθ)^2
Factor the top
[(cosθ-1)^2]/(sinθ)^2
The Answer to this Question is:
(2x^2+3y)(4x^4-6x^2y+9y^2)
This symbol ^ means that the number after is an exponent.
Answer:
use identity (a - b) ^3 = a^3 - b^3 - 3ab (a - b)
here, a = x ^2
b = -1
= (x^2)^3 - (-1)^3 - 3 * x ^2 * -1 ( x^2 - (-1) )
x^6+ 3 x^2 ( x ^2 + 1)
I think this is the answer
22 unit cubes and 2 smaller cubes of volume cubic inch each
