The sign only changes when divided or multiplied by a negative number.
Answer:
-7x^3+8x^2+x-5
Step-by-step explanation:
We are simply adding the two functions:
f(x) + g(x) = (2x^2-5x^3+x-7) + (6x^2-2x^3+2) = 8x^2-7x^3+x-5 = -7x^3+8x^2+x-5
Answer:
Just plus everything together
X-3+4X+4+2X+1
Step-by-step explanation:
Answer:
12
Step-by-step explanation:
the length of one leg of the given isosceles triangle is 12.
we get it by using pythagorous theorem
Each time multiplied by 6/5
the common ratio is 6/5
since |6/5|>1, the series does not converge to a single number and the sum approaches positive infinity
there is no real number that the sum of this series approaches
