Answer:
y = (-4)
Step-by-step explanation:
Given equation is,
-2y = 4y + 24
By subtracting 4y from both the sides of the equation,
-2y - 4y = (4y + 24) - 4y
-6y = 24
By dividing the equation by (-6),
y = (-4)
Step-by-step explanation:
Hope this helps:) ジョセフ

Answer:
Цилиндр_R = OC = OB = 10 см Сечение ABCD - квадрат : AB=BC = CD
= AD
ON=8 см и ONLCB
ДCON- прямоугольный : ZONC = 90°;
OC = 10 см; ON = 8 см Теорема Пифагора
CN² = OC² - ON² = 10² - 82 = 36 = CN
= √36 = 6 см
ДВОС- равнобедренный, ONLCB →
CN = BN
CB = 2 CN = 2*6 = 12 cm
BD - диагональ квадрата BD = CB*√2 = 12√2 cm
Диагональ сечения 12√2 CM
