User: A rectangle with a length of x - 4 and a width of 8 has a perimeter of 34. What is the value of x?

Weegy: the length equals: w + 4. width = 6.5 inches; length = 10.5 inches.

User: What is the slope of a line that runs parallel to y = 2x + 5?

Weegy: This is an easy mathematical problem. In order to find the slope and the Y intercept of the equation all you need to do is bring the equation in the general form, y = mx + c. It will become y = 2x - 5. [ In this case as we can see 2 is the slope and -5 is the y intercept. ]

User: Simplify 2x2 + 7x - 4x - 6x2.

A rectangle with a length of x - 4 and a width of 8 has a perimeter of 34. Then 2(x - 4) + 2(8) = 34
2x - 8 + 16 = 34
2x + 8 = 34
2x = 34 - 8 = 26
x = 13

2x^2 + 7x - 4x - 6x^2 = -4x^2 + 3x

Exponential Decay is A model for decay of a quantity for which the rate of decay is directly proportional to the amount present.
