Step-by-step explanation:
Let us briefly explain the terms
- Variable: This is the letter in the expression
- Coefficient: This is the number beside the letter above
- Constant: This is a number without any variable attached.
Let us take our expression with two terms to be: 3x+5
Coefficient =3
Variable =x
Constant =5
The word phrase of the expression is:
5 added to the product of 3 and a number.
x= -623/18
Hope it helps for you,buddy!
Answer:
B and F
Step-by-step explanation:
Given
x² + 4x + 4 = 12 ( subtract 4 from both sides )
x² + 4x = 8
Using the method of completing the square to solve for x
add ( half the coefficient of the x- term )² to both sides
x² + 2(2)x + 4 = 8 + 4, that is
(x + 2)² = 12 ( take the square root of both sides )
x + 2 = ± 
( subtract 2 from both sides )
x = ± - 2
= ± 2
- 2
Hence
x = 2 - 2 → B
x = - 2 - 2 → F
To work out the distance of the path, you need to find out the circumference.
Formula for circumference = pi multiplied by the diameter
So you simply do:
pi multiplied by 1.4 miles
And you should get:
4.39822971503... miles
Simply round the result to an appropriate value (e.g. 3 decimal places).
Answer: 4.398 miles (to 3dp)
Hope the answer helps :)
