The coordinate of A is -5x. The coordinate of Z is 4+x. AZ=16. Find the value of x and the coordinate(s) of A.

I tried out the problem, and found out that x=2.

I can't figure out the coordinates of A though :/.

My teacher told us to use absolute value, but I don't know how...

I am doing a biology lab were seeds are grown in the dark and light. Seeds grown in the dark become longer but light grown seeds develop more biomass over time. I get all that stuff. But how then would you define growth?

Ok, so I have a triangle of sides 330, 270, and 240, and there is a circle of maximum area within this triangle. This circle has an area of 18200, and thus a radius of 76.11333608. How can I find the equation of this circle?

Ok so the question is Can plants grow in a dark environment with only a small amount of sunlight? This is my son's project. So we did the project. Put 2 plants in boxes with a small hole at the top and put the 3rd plant in the light. A&B (the plants in boxes grew faster) and C (the one in the sun ) grew a little slower, but was definetly in better condition. ( I know this is because clorophyll absorbes energy from the sun which gives the plants it's green color). The other 2 in the boxed grew taller (trying to reach for the light and climbed out of the top of the box) although the stems are pale. So can the plants still survive with only a small amount of light or will they eventually die? Best answer gets 10 pts
