Step-by-step explanation:
Solution:
(6xy) × (-3x²y³)
= {6 × (-3)} × {xy × x²y³}
= -18x1+2 y1+3
= -18x³y⁴.
This is what we know:4x^2 + 12x + c = (2x + k)^2

4x^2 + 12x + c = 4x^2 + 2kx + 2kx + k^2
c=9

Answer:
m = 12.728 or 18/root (2)/2, n = 9
Step-by-step explanation:
To find m, we can use sin(45) and cos(45).
Since sin(45) = root (2)/2 and this equals 9/m.
We set the equation root (2)/2 = 9/m and solve for m.
9 divided by root (2)/2 would give us 18/root (2), or 12.728.
m is 12.728.
Same process for n but we are using cosine this time.
cos(45) = root (2)/2 and this equals n/12.728.
Solving for n would give us root (2)/2 times 12.728.
This gives us that n is 9.
10, because 100 divided by 10 is 10
