Evaluating the function,f(x) = –2x² – 3x + 5 for x = -3, we would have: f(-3) = -4. (option B).
To evaluate a function, plug in the given value of the input (x) and simplify.
Thus:
f(x) = –2x² – 3x + 5
Substitute x = -3 into the function
f(-3) = –2(-3)² – 3(-3) + 5
f(-3) = -2(9) + 9 + 5
f(-3) = -4
Therefore, evaluating the function,f(x) = –2x² – 3x + 5 for x = -3, we would have: f(-3) = -4. (option B).

To simplify the square root of 40, first notice that 40 is not a perfect square. We can start by setting up a factor tree. 40 factors as 2 times 20. 20 factors as 2 times 10 and 10 factors as 2 times 5. There is a pair of two's so this means that a two can come out of the radical. The 2 and the 5 do not match up so they will stay inside the radical. If you multiply them together you will make 10.
Therefore, the square root of 40 simplifies to 2 root 10.

The numerical expression √40 in the simplified form will be 2√10.
Given that:
Number, n = √40
Algebra is the study of algebraic expressions, while logic is the manipulation of those concepts.
It is a method for dividing a number into pieces that will be multiplied together.
The factors of the number 40 are calculated as,
40 = 2 x 2 x 2 x 5
40 = 2² x 10
The expression is simplified as,
√40 = √(2² x 10)
√40 = √(2)² x √10
The square root is canceled out by a square. Then the numerical expression is written as,
√40 = √(2)² x √10
√40 = 2 x √10
√40 = 2√10

Using trigonometry property, the best option is B.
Trigonometry deals with "the relationship between the sides and the angles of triangles".
According to the question,
[tan x + cot x] (sin x + cos x) = 1
[tan x =
and cot x =
]
[By cancellation law]
By the Pythagoras theorem, .
Hence, using trigonometry property, the best option is B.
