I keep ending up with x^2+4x=0 and don't know what to do from there, please help!

I have recently noticed that I have a mole and am wondering if I should get it checked out by a doctor?

Online it says that you should check for symmetry, color, size, and the border. My mole is not symmetrical, the borders fade out, and it is bumpy. However, they say that this kind is usually skin cancer and it comes from not wearing sun screen. However, I know that it has never seen sunlight, much less burned badly or often. I was wondering is I should be concerned about it?

Since I was very young my family has always thought I was lactose intolerant, but we never went to a doctor for it. Whenever we'd go out for ice cream I would get very sick. However, recently I have been wondering if it is really lactose intolerance. I still get sick from ice cream, but I can eat milk with my cereal and I have no trouble with yogurt. I read that if you are really intolerant you can't handle anything, whereas with me it is mainly the ice cream. I was wondering if anyone knew something else this could be?

Flights of leaping animals typically have parabolic paths. The length of the leap is 9 feet, and the maximum height off the ground is 3a feet. Find a standard equation for the path of the frog. Assume a = 0.5.

Please help, I keep coming up with y=.5(x-4.5)^2+1.5 and it says that's wrong.

A farmer wishes to put a fence around a rectangular field and then divide the field into three rectangular plots by placing two fences parallel to one of the sides. If the farmer can afford only 1000 yards of fencing, what dimensions will give the maximum rectangular area? (If there are any unused answer boxes, enter NONE in the last boxes.)

What are the short side and longer side?

Please help!

An object is projected vertically upward from the top of a building with an initial velocity of 128 ft/sec. Its distance s(t) in feet above the ground after t seconds is given by the equation

s(t) = −16t^2 + 128t + 110.

(a) Find its maximum distance above the ground.

Please help! I can't find this anywhere

A baseball is thrown straight upward with an initial speed of 128 ft/sec. The number of feet s above the ground after t seconds is given by the equation

s = −16t^2 + 128t.

A. When will the baseball be 192 feet above te ground?

B. When will it hit the ground?

A box with an open top is to be constructed by cutting a-inch squares from the corners of a rectangular sheet of tin whose length is twice its width. What size sheet will produce a box having a volume of 528 in3 when a = 3?

Width = ?

Length = ?

A water tank can be emptied by using one pump for 4 hours. A second, smaller pump can empty the tank in 7 hours. If the larger pump is started at 1:00 P.M., at what time should the smaller pump be started so that the tank will be emptied at 4:00 P.M.?

A salesperson purchased an automobile that was advertised as averaging 25 mi/gal in the city and 40 mi/gal on the highway. A recent sales trip that covered 2300 miles required 62 gallons of gasoline. Assuming that the advertised mileage estimates were correct, how many miles were driven in the city?
