Answer:
In one Pb&j it is 385 and in three it has 1,155 (385×3=1,155 )
The polynomials are closed under subtraction when polynomial 5x − 6 is subtracted
from is
will be a polynomial.
<h3>What is polynomial?</h3>
Polynomial is an algebraic expression that can involve variables with nonnegative integer terms and constants.
Given
Polynomial 5x -6 and
.
Similar terms are terms having the same variables with the same degree.
- When we subtract polynomials, we combine like terms: 3x² is the only x² term.
- We have -6x and subtract 5x from it; this gives us -11x.
- We have 2 and subtract -6 from it; when we subtract a negative, we add the opposite, which means we have 2--6=2+6=8.
Therefore,
The polynomials are closed under subtraction when polynomial 5x − 6 is subtracted from 3x2 − 6x+ 2 is;

Hence, the polynomials are closed under subtraction when polynomial 5x − 6 is subtracted
from is
will be a polynomial.

Answer:
C.
Step-by-step explanation:
Hello,
f(x,y)=2(x²+y²)-25(x²-y²)=0(1)
@f/@x=2*2*(x²+y²)*2x-50x
@f/@y=2*2*(x²+y²)*2y-50y
dy/dx=-(@f/@x)/(@f/@y)=0
==> 2x*(4x²+4y²-25)=0
==>x=0 or x²+y²=25/4 (2)
As (1)==>2*25/4-25(x²-y²)=0
==> x²-y²=1/2 (3)
(2) and (3)=>2x²=27/4 ==>x²=27/8 and y²=23/8
==>x=-√(27/8) and (y=-√(23/8) or y=+√(23/8)
or x=√(27/8) and (y=-√(23/8) or y=+√(23/8)
Answer:
61
Step-by-step explanation:
82+37=119. 180-119=61. remember triangles always add up to 180°
