<em>Answer:</em>
for question 4 the asnwer is 1.7
for question 6 the answer is 2
<em>Explanation: </em>
The volume of 4 is 18 length × width × height so 3 × 3 × 2 = 18
The mass 32kg divided by the volume 18 = 1.777777778
-----------------------------------------------------------------------------------------------
The volume of 6 is 90 length × width × height so 10 × 3 × 3 = 90
The mass 180kg divided by the volume 90 = 2

A triangle is 180°; therefore:
x = 180-52-43
x = 85
x° = 85°
Assuming that you were to simplify this, you'd get 2n + 7n + 8 = 9n + 8.
