Find 3 consecutive even numbers where the product of the smaller two numbers is 40 less than the square of the largest number.

Marina86 [1]

$3\ consecutive\ even\ numbers:\ 2x,2x+2,2x+4\\\\2x(2x+2)+40=(2x+4)^2\\\\
4x^2+4x+40=4x^2+16x+16\\\\
4x^2-4x^2+4x-16x=16-40\\\\-12x=-24\ \ |:(-12)\\\\x=\frac{24}{12}=2\\\\2x=2=4\\\\2x+2=6\\\\2x+4=8\\\\Numbers\ are\ 4,6,8.$

Draw the graph of y = 2x - 5 for -3<img src="https://tex.z-dn.net/?f=%5Cleq%20x%5Cleq%20-5" id="TexFormula1" title="\leq x\leq -

11Alexandr11 [23.1K]

Answer and Step-by-step explanation:

I will be using Desmos to show you the graph.

So, draw your line from the equation, and then lightly shade the left and ride side. That middle side is where there is no solutions for -3 ≤ x ≤ -5 for y = 2x - 5.

The parts that are shaded have the solutions.
