Answer: A. 2x2 - 3x - 8
Just subtract the functions and combine like terms
(f - g)(x) = f(x) - g(x)
(f - g)(x) = 2x^2 - 5 -(3x + 3)
(f - g)(x) = 2x^2 - 5 - 3x - 3
(f - g)(x) = 2x^2 - 3x - 8
I would simply solve the fraction as a division question. To divide 36 by 10, just move the decimal one place to the left. That gives you 3.6
Answer:
B
Step-by-step explanation:
Answer:
Volume of square-based pyramid = 96 in³
Step-by-step explanation:
Given:
Base side of square = 6 inch
Height of pyramid = 8 inch
Find:
Volume of square-based pyramid
Computation:
Area of square base = Side x Side
Area of square base = 6 x 6
Area of square base = 36 in²
Volume of square-based pyramid = (1/3)(A)(h)
Volume of square-based pyramid = (1/3)(36)(8)
Volume of square-based pyramid = (1/3)(36)(8)
Volume of square-based pyramid = (12)(8)
Volume of square-based pyramid = 96 in³
Notice that the 2 expressions have 2 common terms.
(r-s) is just (s-r) times (-1)
similarly
(t-s) is just (s-t) times (-1)
this means that :
(r-s) (t-s) + (s-r) (s-t)=-(s-r)[-(s-t)]+(s-r) (s-t)
the 2 minuses in the first multiplication cancel each other so we have:
-(s-r)[-(s-t)]+(s-r) (s-t)=(s-r) (s-t)+(s-r) (s-t)=2(s-r) (s-t)
