Answer:
C
Step-by-step explanation:
Step-by-step explanation:
Since x² + kx + (k + 3) is tangent to the x-axis, the quadratic function has a repeated root.
The discriminant is zero, so b² - 4ac = 0.
=> k² - 4(1)(k + 3) = 0
=> k² - 4k - 12 = 0
=> (k - 6)(k + 2) = 0
Hence k = 6 or k = -2.
To start you add the 2 x and 2 p so you have 2p times 2x times 4
Answer:
w = 12ds/x
Step-by-step explanation:
Here, we want to write the equation in terms of w
What we simply do here is to bring x and w to reach others side
we have this as;
w = 12ds/x
