Step-by-step explanation:

Question 3:

$b + 2 \geq 4\\b + 2 -2 \geq 4 - 2\\b \geq 2\\$

Question 4:

$13 > 18 + r\\13 - 18 > 18 -18 + r\\\\-5 > r\\ r < -5$ sign flips when r switches sides

Question 5:

$3y \leq 2y - 6\\3y - 2y \leq 2y - 2y - 6\\\\y \leq - 6\\$

Two poles,A and B, are 12 meters apart. Pole A is 5 meters high. A rope 20 meters long is tied to the top of pole A and stretche

timurjin [86]

We will use the Pythagorean theorem:
c² = a² + b²
b² = c² - a²
x² = 20² - 12²
x² = 400 - 144
x² = 256
x = √256
x = 16
The pole B : 16 m + 5 m = 21 m
Answer: C ) 21 m
