Answer:
sorry i dunno
Step-by-step explanation:
By the knowledge and application of <em>algebraic</em> definitions and theorems, we find that the expression - 10 · x + 1 + 7 · x = 37 has a solution of x = 12. (Correct choice: C)
<h3>How to solve an algebraic equation</h3>
In this question we have an equation that can be solved by <em>algebraic</em> definitions and theorems, whose objective consists in clearing the variable x. Now we proceed to solve the equation for x:
- - 10 · x + 1 + 7 · x = 37 Given
- (- 10 · x + 7 · x) + 1 = 37 Associative property
- -3 · x + 1 = 37 Distributive property/Definition of subtraction
- - 3 · x = 36 Compatibility with addition/Definition of subtraction
- x = 12 Compatibility with multiplication/a/(-b) = -a/b/Definition of division/Result
By the knowledge and application of <em>algebraic</em> definitions and theorems, we find that the expression - 10 · x + 1 + 7 · x = 37 has a solution of x = 12. (Correct choice: C)

Answer:
5 miles
Step-by-step explanation:
1 meter is 0.000621371 mile
So you multiply
8,046.72 x 0.000621371 = 5
we have
we know that
If the point is an equation solution, it must satisfy the equation.
<u>case a</u>) 
Substitute the values of x and y in the equation
-------> the point is not solution of the equation
<u>case b</u>) 
Substitute the values of x and y in the equation
-------> the point is solution of the equation
<u>case c</u>) 
Substitute the values of x and y in the equation
-------> the point is not solution of the equation
<u>case d</u>) 
Substitute the values of x and y in the equation
-------> the point is not solution of the equation
therefore
<u>the answer is</u>
The point is solution of the equation
So the area of a rectangle is Length x Width.
A = (L)(W)
Substitute the information given:
4x^2 + 20x + 16 = (L)(2x+8)
Isolate L by dividing 2x+8:
(4x^2 + 20x +16)/ (2x + 8) = L
If you divide:
L = 2x + 2.
