Answer:
D.648 inches
Step-by-step explanation:
A yard is a unit that mostly used in America and Canadia to measure the length of something field-size, so it's used a lot in sport. One yard equal to three feet, while one foot equals to 12 inches. There is a higher unit than yard called miles which equals to 1760 yards or 1.60934 kilometers.
Since the measurement is 18 yards, the length in feet will be: 18 yards * 3 feet/yard= 54 feet.
The measurement in inch will be: 54 feet * 12 inches/feet = 648 inches.
Answer:
First option
Step-by-step explanation:
There's no value of x which makes the function undefined .
So x can take any real value
i.e. -infinity < x < +infinity
7(6) x 7(5) = 7(6+5) = 7(11) is the simplified answer.
Thank you!
F(x) = x(x -1)
f(3) = 3*2 = 6
f(6) = 6*5 = 30
so f(f(3)) = 30 . . . . . selection A
