Answer:

Step-by-step explanation:

20 can be written as a product of 4 and 5.

4 is a perfect square.

Square root of 4 is 2.

Basically it’s asking when is the function g(x) greater than the function of f(x), which are both graphed on the graph. g(x) needs to be above f(x) for it to be greater, and that is shows between 0-2 and 4+, making the answer A
S = 2*(1/2 * 7 * 14) + 2* (1/2 * 7 * 7) = 7*14 + 7*7 = 7*(14+7) = 7*21 = 147 sm^2
Number B
Answer is x = (355*r^-35)/7 hope led me know if you have any questions
