Find the results combining these functions.

vodomira [7]

Given $f(x) = x^2 + 6x + 9, g(x) = x^2 - 9$ :

$(f+g)(x) = (x^2 + 6x+9)+(x^2-9) =2x^2+6x=2x(x+3)$ , which is the second expression

$(f-g)(x) = (x^2 + 6x+9)-(x^2-9) =6x+18=6(x+3)$ , which is the first second expression

$(fxg)(x) = (x^2+6x+9)(x^2-9) = (x^4-9x^2)+(6x^3-54x)+(9x^2-81)=x^4+6x^3-54x-81$ , which is the fourth expression

$(f/g)(x) = (x^2+6x+9)/(x^2-9) = \frac{(x+3)^2}{(x+3)(x-3)} = \frac{x+3}{x-3}$ , which is the third expression

What is the value of x?<br> Enter your answer, as a decimal, in the box.

RideAnS [48]

Answer:

x = 67.5 ft

Step-by-step explanation:

In ΔNMP

∵ AB // NP

∴ m∠ MAB = m∠MNP

∴ m∠MBA = m∠MPN

∵ ∠M is a comman angle

∴ ΔMAB is similar to ΔMNP

∴ MA/MN = MB/MP

∵ MA = 71.5 - 22 = 49.5

∴ 49.5/71.5 = x/97.5

∴ x = $\frac{(49.5)(97.5)}{71.5}$ = 67.5
