given the function f(x)=x^2+2x+1, find:
f (2a−3)/5

Step-by-step explanation:

f(x)=x²+2x+1,

f (2a−3) = (2a-3)² +2(2a-3) +1

            = 4a² - 12a +9 +4a -6 +1

f (2a−3) = 4a² - 8a +4

f (2a−3) /5 = (4a² - 8a +4)/5

step-by-step explanation:

i found the koficent of the linear function and i foun c acordind to the strict formula y=kx+c and then i took 2 as an x and replacet it on the formula i found and then foun the y

14 ft 7 inches

step-by-step explanation:

since each model inch corresponds to 25 real inches, 7 model inches will correspond to

7×25" = 175"

at 12" per foot, that is 14 feet, 7 inches.
