Answer:
45x - 63 y + 36 z
Step-by-step explanation:
When I think of the distributive property, I imagine giving the outside term to everyone on the inside (multiplying).
9 (5x - 7y + 4z)
= 9 (5x) + 9 (-7y) + 9 (4z)
= 45x - 63 y + 36 z
Good luck with your math!
Step-by-step explanation:
sin30° = x/14
1/2 = x/14
1/2 × 14 = x
x = 7
cos30° = y/14
squareroot3/2 = y/14
0.866 = y/14
y = 0.866 × 14
y = 12.124
