Answer:
f(x)=x^2+3
f(x+y)=(x+y)^2+3
this is done by replacing x with (x+y)
f(x+y)=x^2+2xy+y^2+3
therefore : f(x+y)= x^2+y^2+2xy+3
Answer:

Step-by-step explanation:
The slope formula is 
Here,
is -6,
is 4,
is -5, and
is 4.


So, the slope of the line passing through the points (-6,-5) and (4,4) is
.
The Last on = 45x^2 - 2x - 8
Reason being is because you would group and multiple:
(9x - 4) • (5x +2)
Answer:
8
Step-by-step explanation:
let the numbers be x,x+1,x+2
x+x+1+x+2=27
3x+3=27
3x=27-3=24
x=24/3=8
above, -6 and -<span>1 2x2</span> - 6x - 1x - 3. Step-4 :
