Answer:
f(x) = (x + 1)(x + 2)
Step-by-step explanation:
Given
f(x) = x² + 3x + 2
Consider the factors of the constant term (+ 2) which sum to give the coefficient of the x- term (+ 3)
The factors are + 1 and + 2, since
1 × 2 = 2 and 1 + 2 = 3, thus
f(x) = x² + 3x + 2 = (x + 1)(x + 2)
Answer: it would be P=4n
She drove a 122.5 miles
sin 105 = sin (45 + 60) = sin 45 cos 60 + cos 45 sin 60, or
= (1 / √2)(1 / 2) + (1 / √2)(√3 / 2)
1 + √3
= -------------
