Answer:
no
Step-by-step explanation:
you multiply straight across on top and bottom then you simplify :)
Answer:
x ≤ 3
Step-by-step explanation:
2(4+2x) ≥ 5x+5 (by PEDMAS, expand parentheses first)
4(2) + 2x(2) ≥ 5x + 5
8 + 4x ≥ 5x + 5 (subtract 8 from each side)
4x ≥ 5x + 5 - 8
4x ≥ 5x - 3 (subtract 5x from both sides)
4x -5x ≥ - 3
-x ≥ - 3 (multiply both sides by -1, remember to flip the inequality when multiplying both sides by a negative number)
x ≤ 3
Answer: 50.85 meters
<u>Step-by-step explanation:</u>
cos 29 = 
55 cos 29 = h
48.10 = h
Pole = h + 2.75
= 48.10 + 2.75
= 50.85
