2x²yz - 7xy²z + 13xyz² - 6 from 4xyz² + xyz - 6x²yz + 9xy²z

Step-by-step explanation:

We are given with two different polynomials in the question to subtract the second expression with the first. The word from determines that, the second expression should be subtracted by the first. So,

from

So, now we can solve these,

Now, we should group the like terms.

Therefore, the final anwer is,

Therefore, the final anwer is,-9xyz² - 8x²yz + 16xy²z + 6 + xyz.

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !

but which class are u may know that first
