Answer:
n= -28
Step-by-step explanation:
n+13= -15
n+13-13= -15-13
n= -28
Answer:
21 is a composite number
Step-by-step explanation:
It is a composite because multiple numbers can go in it like 3 and 7 so it is a composite number
First you put (x+5) into the initial function wherever you see x so it becomes
(x+5)^2+3(x+5)-10=x^2+kx+30
(x^2+5x+25)+(3x+15)-10 simplified left side
x^2+8x+30 fully simplified left side
thus k=8
x^2+8x+30=0 to find 0s
-4 + 3.7416573867739i

</span>these are the roots you find after using the quadratic formula
the second one is the smallest
