Answer:
24 ( 12 -3x)
Step-by-step explanation:
(4x3 + 7x2 – 2) (2x2 – 3x + 8)
(12 + 14 - 2) (4 - 3x + 8)
(26-2) (12 - 3x)
24 (12 -3x)

Answer:
9.404 cm
Step-by-step explanation:
A regular polygon with n sides inscribed in a circle of radius r will have a side length given by ...
s = 2r·sin(180°/n)
For r = 8 and n = 5, this gives a side length of ...
s = 2·8·sin(180°/5) = 16·sin(36°) ≈ 9.404 . . . cm
Answer:
-7°C
Step-by-step explanation:
Freezing point of water = 0°C
By adding salt, freezing point lowers by 7°C ;
The freezing point of salt water can be expressed as ;
Since temperature lowers :
Freezing point of salt water :
Freezing point of water - 7°C
0°C - 7°C
= - 7°C
