Answer:
946
Step-by-step explanation:
xyz- the searched number where x depicts hundreds, y - tens and z describes ones. Both X and Z are divisible by 3 .Y and Z are divisible by 2
Z is divisible by 3 and divisible by 2, the only digit which is possible is 3*2=6
6-2=4 - tens digit Y
The hundreds place digit is 3*3=9
S0 946- is an answer
2y-6=8x+4
+6 will cancel out on the left...
2y=8x+10
divide by 2 to get y=4x+5
Finally, you would make a graph, to find x=1 and y=9
1.08 km^2 you get this by converting 900 meters to .9 km and then just multiply the 2 numbers together to get the area
Answer:
x=47
Step-by-step explanation:
If the total degrees in a triangle is 180 then you would just add the given values and subtract it from 180.

Answer:
A. 2x^2 +4
B. 5x^3 -4x^2 +3x -12
C. addition and subtraction of polynomials result in polynomials (closed)
Step-by-step explanation:
A. The total of the two side lengths is ...
(3x^2 -4x -1) +(-x^2 +4x +5) = (3 -1)x^2 +(-4+4)x +(-1+5) = 2x^2 +4
__
B. The length of the third side is the difference between the total for all three sides and the total for the given two sides:
(5x^3 -2x^2 +3x -8) - (2x^2 +4) = 5x^3 +(-2-2)x^2 +3x +(-8-4)
= 5x^3 -4x^2 +3x -12
__
C. Addition of the two polynomials results in a polynomial. Subtraction of the two polynomials results in a polynomial. There is nothing here to indicate the set of polynomials is not closed under addition and subtraction.
