If f(x)=3(x+5)+4/x, what is f(a+2)?

3(a + 7) + 4/(a + 2)

Step-by-step explanation:

f(x) = 3(x + 5) + 4/x

Substitute:

x = a + 2

f(a + 2) = 3(a + 2 + 5) + 4/(a + 2)

= 3(a + 7) + 4/(a + 2)

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
