Answer:
Step-by-step explanation:
x²+2 ×x×5+5²=-20x+2×x×5-3
(x+5)²=-20+10x-3
(x+5)²=-10x-3
Answer:
Distance = 21.0049 inches
Step-by-step explanation:
Given the following data;
Speed = 3.395 inches per minute.
Time = 6.187 minutes
To find the distance;
Distance = speed * time
Substituting into the equation, we have;
Distance = 3.395 * 6.187
Distance = 21.0049
These questions just take some trial and error. Try a bunch of things. After about 2 minutes I came up with
(16 + 5) / (2 - 1 + 6)
You can check this by simplifying everything inside the brackets.
21 / 7
= 3
Find the circumference of the metal frame?
C = pi * d
Where 'd' is the diameter.
In this case, the diameter is 14, because that is the given information from the question.
Plug it in along with 3.14 for pi:
C = 3.14 * 14
C = 43.96
So it's approximately 44
