Answer:
Step-by-step explanation:
2√54+5√24
2 * sqrt(9*6) + 5*sqrt(4*6)
2*sqrt(9) *sqrt(6) + 5*sqrt(4) * sqrt(6)
2*3 sqrt(6) + 5*2 sqrt(6)
6sqrt(6)+10sqrt(6)
16sqrt(6)
Answer: -2,3,&4
Step-by-step explanation:
Correct on edgenuity
The ascending or descending order of a polynomial is
determined by the increasing or decreasing power of variable “x” respectively.
<span>The question is to find about the polynomial in
descending order, so in this case, the 3rd option is correct, i.e.
4x^2 – 3x + 9 or 4x^2 – 3x^1 +9x^0. The power of “x”
decreasing from 2 to 1 and then finally to 0.</span>
First of all, since all powers of x in this function are even, the entire function is even. Thus, using -x as input doesn't change the function. Thus, f(-x)=2x^2-4.
