Step-by-step explanation:
Answer:
4.
f(x) = (x + 2)(x + 1)(x - 3) = x^3 - 7·x - 6
a = 0 ; b = -7 ; c = -6
5.
a = -3 ∧ b = -2 ∧ c = -3
Answer:
D 40,000nm
Step-by-step explanation: 1nm/10^-9m * 10^-6/1um = 10^3 nm/um
Therefore in 40 microns there are:
40um * 10^3 nm/um = 40 * 10^3 nm = 40,000 nm
The answer is negative 5 because you subtract 12 from each side to get 5x=-25 and -25 divided by 5 is negative 5
Answer:
9/20
Step-by-step explanation:
1/4 + 2/10
We can simplify 2/10 to 1/5 by dividing the top and bottom by 2
1/4+1/5
The common denominator is 20
1/4 *5/5 + 1/5*4/4
5/20 + 4/20
9/20
