For the polynomial 6xy2 – 5x2y? + 9x2 to be a trinomial with a degree of 3 after it has been fully simplified, the missing exponent of the y-term must be ?

The missing exponent of the y-term must be 1.

is a trinomial with a degree of 3 after it has been fully simplified

Step-by-step explanation:

 Given :  The polynomial be a trinomial with a degree of 3  after it has been fully simplified.

We have to find the value of the missing exponent of the y-term that is a.

Consider the Given polynomial

Since after simplification a trinomial is obtained so the  missing exponent of the y-term in the polynomial  

Since the degree of polynomial is 3.

So the highest power of the polynomial has to be 3 and rest terms have power less than 3.

In , , has highest power 3 (1+2) so the combined power of has to be three or less than 3.

And power of y must lies in between 0 ≤ a ≤ 1

If power of y is 0 then  becomes becomes an simplified to   which is not trinomial.

Hence  a has to be 1.

So that   becomes   which is a trinomial with a degree of 3 .

Thus, the missing exponent of the y-term must be 1.

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.

answer: 10 turtles

step-by-step explanation: as turtles have four legs so 4.10=40 therefore birds are 4 which sue counted
