Answer: 362880
The exclamation mark means factorial notation. The rule is we start with the given number, then count down til we get to 1, multiplying all along the way. In this case, we start with 9, then multiply with 8, 7, 6, etc til we get to 1, like so...
9! = 9*8*7*6*5*4*3*2*1 = 362880
Some calculators have a factorial button built in. The button should be labeled with an exclamation mark.
F(x)=x^2+2x-10
f(-2)=4-4-10
f(-2)=-10
the answer is A) or -10

Step-by-step explanation:
Answer:
(2x + 1)(3x + 2)
Step-by-step explanation:
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 6 × 2 = 12 and sum = 7
The factors are + 3 and + 4
Use these factors to split the x- term
= 6x² + 3x + 4x + 2 ( factor the first/second and third/fourth terms )
= 3x(2x + 1) + 2(2x + 1) ← factor out (2x + 1) from each term
= (2x + 1)(3x + 2) ← in factored form
