Answer:
that looks correct but if not it would be B
Step-by-step explanation:
Answer:
k<0 or k>4
Step-by-step explanation:
In the generic equation ax² + bx + c = 0, there are two solutions only if discriminant D>0 where D = b²-4ac.
Mapping your equation on the generic means that:
a = k
b = k
c = 1
So when we have to solve D>0 we solve:
k² - 4k > 0
k(k-4) > 0
roots are k=0 and k=4
k² - 4k > 0 when k<0 or k>4
Answer:
50
Step-by-step explanation:
P () Parentheses
E ^exponents
M * multiplication
D / division
A + addition
S - subtraction
You have to go step by step in order
5*8=40+10=50
