The required trinomial that has 9x² has GCF of its terms is 9x²(x + y + z).
A polynomial function is a function that applies only integer dominions or only positive integer powers of a value in an equation such as the quadratic equation, cubic equation, etc. ax+b is a polynomial.
Here,
For a trinomial, there must be 3 terms in the expression,
So, a trinomial with 9x² as the greatest common factor is given as
= 9x²(x + y + z).
= 9x³ + xy² + xz
Thus, the required trinomial that has 9x² has GCF of its terms is 9x²(x + y + z).

what is c
9x2 – 25 = (3x – 5)(3x + 5)
9x2 – 25 = –(3x + 5)(3x + 5)
9x2 – 25 = –(3x + 5)(3x – 5)
Answer :
(1)
Use FOIL method to mulitply (3x – 5)(3x – 5)
(2)
Use FOIL method to mulitply (3x - 5)(3x + 5)
(3)
Use FOIL method to mulitply -(3x + 5)(3x + 5)
(4)
Use FOIL method to mulitply -(3x + 5)(3x - 5)
So equation 2 is true
Answer:
<1=83
<2=97
<3= 83 (given)
<4=97
<5=83
<6=97
<7=83
<8=97
Step-by-step explanation:
They give you the angle for 3 which is 83, so from there all you have to do is find the equivalent angles which are angle 1,5,7. Then for angles 2,4,6,8 you subtract 83 from 180 and you get 97.
