Answer:
Step-by-step explanation:
We can write sq root (- 18) as = sq root [3 x 3 x (-2)]
Similarly sq root ( - 8) = sq root [2 x 2 x (-2)]
2 sq root [2 x 2 x (-2)] - 3 sq root [3 x 3 x(-2)]
We simply,
2 x2 sq root (-2) - 3 x 3 sq root (-3)
4 sq root (-2) - 9 sq root (-2)
Bcoz sq root (-2) is common in bot term so
So
Sq root (-2) (4-9)
-5 sq root (-2) answer
The second option because the key word is “product” which means multiplication:)
43 bc there's 1+1+1=3 then look for the number that has a 3 :D
123 meetings. 38,483 divided by 315 equals 122.168254. To have everyone meet, you need 123 meetings.
Answer: 4) x° = 33.5°
5) x° = 31°
Step-by-step explanation: 4) It is supplementary i.e. the angle add up to 180° .
(4x+5)° +41° = 180°
4x+46 = 180°
4x = 180-46 = 134
4x = 134/4 = 33.5°
5) It is complementary i.e. angles add up to 90°
x°+(2x-3)° = 90°
3x - 3 = 90
3x = 93
x = 31°
