Let the length of the first piece be x inches. Then:-
x + 2x + 4x + 3 = 38
7x = 38 - 3
x = 35/7 = 5 inches
Answer: the 3 pieces have lengths 5, 10 and 23 inches.
The answer has to be 1 because anything times 1 in this case 6 has to be its own self.
Answer:
36
Step-by-step explanation:
You take 1/2 the linear term's coefficient and square it.
The linear term is the term that contains just an x and a number -- in this case 12x
Take 1/2 12 = 6
and square it
6^2 = 36
So when you've done that you should get
x^2 + 12x + 36 = 11 + 36
x^2 + 12x + 36 = 47
Do 63*15.75 and you should get your answer
992 1/2
