The gcf of 18 and 20 is 2, so your answer is:
2(9+10)
Answer:
1,620
Step-by-step explanation:
Volume = bh
the base is 15x9 which gives you 135
know you must multiply the base x height
135x12= 1,620
for future length and width = base
Answer:
2 sqrt(3) -2i
Step-by-step explanation:
If we have the magnitude and the theta
z = |z| cos theta + i |z| sin theta
= 4 cos 330 + i 4 sin 330
=4 (sqrt(3)/2) + 4i (-1/2)
= 2 sqrt(3) -2i
Using the equations y-3x=3 and x+y=31 you can find that x=7 and y=24. There for x is the smaller of the two numbers.
