Step 1: move all terms to one side
7 + 2x^2 - 10x = 0
Step 2: Use the quadratic formula
X = 10 + 2(square root of 11). 10-2 _/—-11

True. It is linear because it forms a straight line.
Answer:
10x + 10 units
Step-by-step explanation:
To find the perimeter of a rectangle, you can simply add up the length and width, and then multiply that sum by 2. The sum of the dimensions is 4x + (x + 5) = 5x + 5 and two times that would then be 2(5x + 5) = 10x + 10.
A straight edge, or a right angle, whatever you call it.
If you have sides a, b and c, and c = √(a²+b²), you know that a and b are perpendicular.
