B can be eliminated, as 10x and 4x multiply to 40x^2, which is not in the expression.
The greatest common factor of all coefficients in the equation is 2. Divide all coefficients by 2 to get the following equation:
We will leave out this coefficient, 2, for now.
We'll need to find the factors of c:
c = -6
Factors of 6: {1,2,3,6}
The only factors in the answer choices that fit this are 2 and 3. D can be eliminated.
5x and 2x multiply to 10x^2. 5x and 2x also modify what b will equal. Use the answer choices A and C to find b:
A.
C.
Answer C comes up with the correct b value.
The answer is C. 2(5x - 2)(2x + 3).

Step-by-step explanation:
Answer:
d. 0.4013
Step-by-step explanation:
Half of the area under the normal curve is found to the left of the midpoint, where z=0. For negative values of z, the area under the curve is less than half.
Area under a normal curve is always a positive value between 0 and 1, so will never be negative.
The only value that can be an area in a left-hand tail is 0.4013.
_____
<em>Additional comment</em>
That value corresponds to z ≈ -0.25.
