Answer:
(b-5)(b+6)=0
Step-by-step explanation:
i call it "reverse FOIL"
First we have to assume that each quarter touched each other. Hence the area of the table not covered by the coins (A) is equal to the total area of the table (At) minus the total area of the coins (Ac). Coins are circle, so

and r =24.26mm. The area of one coin is then 1848.98mm^2. Hence the equation is A = At - xAc where x is the number of coins.
Answer:
Step-by-step explanation:
- f(x) = 4x - 2
- f(x - 1) = 4(x - 1) - 2 = 4x - 4 - 2 = 4x - 6
Correct option is D
X^2 + 35x - 450
Factor
(x + 45)(x - 10)
(x + 45) is the length
