Answer:
Step-by-step explanation:
Mass = 780g
Volume = 2 x 5 x 6 = 60 cm³
Density = Mass/Volume
= 780/60
= 13 g/cm³
D. 10
a positive number minus a negative equals a positive
2. Find m
sin m˚ = 2/5
sin^-1 (2/5) = m˚
m˚ = 23.57˚
3. Sine law
Constant
In the polynomial "a(x^2) + bx + c," c is a constant
x = 5
2x + 8 = 18
2x = 10
x= 5
