Answer:
x^2 - 8x + 64 remainder 217 or you could write it as
(x^2 - 8x + 64)+ 217/(x + 8)
Step-by-step explanation:
You first need to write the polynomial in descending order of degree with zero coefficients for x^2 and x terms, so here we have:
x^3 + 729 = x^3 + 0x^2 + 0x + 729
So dividing by x+8:-
x^2 - 8x + 64 <----------the quotient.
x + 8 ) x^3 + 0x^2 + 0x + 729
x^3 + 8x^2
- 8x^2 + 0x
-8x^2 - 64x
64x + 729
64x + 512
217 = Remainder.
I’m pretty sure it’s
6x-10y+x^2-21
Unless I read it wrong then sorry
Answer:
Step-by-step explanation:
The given relation is
To make 
the subject, we square both sides of the equation to get;
Isolate on one side of the equation;
Or
We take the positive square root of both sides to get;
It is an acute triangle since all the sides are less than 90 degrees (it's also equilateral)
