Answer:
28.80
Step-by-step explanation:
I took the test on edge 2020
Answer:
y² - (K- 2)y + 2k +1 = 0
equal roots means D=0
D= b^2 - 4ac
a=1, b= (k-2), c= 2k+1
so,
(k-2)^2 - 4(1)(2k+1) = 0
=> k^2 +4 - 8k -4 = 0
=> k^2 -8k = 0
=> k^2 = 8k
=> k= 8k/k
=> k = 8
Therefore the answer is k= 8
Hope it helps........
I'm pretty sure this is correct
Your answer should be 314
4 x 16=64
10 x 25 (25 is the height)=250
64 + 250=314
