Answer:
1/2
Step-by-step explanation:
quadratic equation is ax²+bx+c=0
Products of roots is c/a
Sum of roots is -b/a
On comparing the above equation with general equation we have
a=1
b=-(3k)
c=-(k+2)
Now it is given that sum of roots and product of roots is equal
So,
-b/a=c/a
-b=c
-[-(3k)]=-(k+2)
3k=-k-2
3k+k=-2
4k=-2
k=-1/2
Answer:
$3240
Step-by-step explanation:
hope it is well understood
Triangle
1+1+5=7
7×4=28
28÷2=12
rectangle
12×5=60
whole shape
60+12=72in squared
V=7 and v=5 because since it says less than or equal to it has to be a number less than 7 or a number equal to 7
