Answer:
The distributive property states that the product of an expression and a sum is equal to the sum of the products of the expression and each term in the sum. For example, a(b + c) = ab + ac. Equivalent. Equivalent means equal in value or meaning.
Perimeter is the sum of all sides of a two-dimensional shape. Therefore, we can construct the following equation to find the value of X:
2x + 4 + 2x + 2 = x + 7 + x + 3 + x + 9
4x + 6 = 3x + 19
4x - 3x = 19 - 6
x = 13
If the perimeter of these shapes is the same, whatever which of them we use for calculating we will find the same result.
Rectangle:
13 + 2 + 13 + 2 + 13 + 1 + 13 + 1 = 58
Or
Triangle:
13 + 7 + 13 + 3 + 13 + 9 = 58
The perimeter is 58.
Well,
If the slope of the lines are the same, then the lines are parralel.
We need to manipulate 2y - 10x = 4 into y = mx + b form.
Add 10x to both sides
2y = 10x + 4
Divide both sides by 2
y = 5x + 2
Do the same thing with the other equation.
Add 2 to both sides
y = 5x + 2
y = 5x + 2
It appears that, not only are they parallel, but they lie on exactly the same line! If this was a System of Simultaneous Linear Equations, then there would be an infinite number of solutions!<span />
First multiply every thing by 7 to get rid of the fraction.
(y/7)(7) +6(7)=11(7)
y+42=77
y=35
