Please take a look at my AP bio question from last night. I still need help! Thanks

A large painting in the style of Rubens is 3 feet longer than it is wide. If the wooden frame is 12 in wide and the area of the picture frame is 208 ft^2, find the dimensions of the painting. So I know the width would be x and the length would be x+3 if I...

Hi here is my question: Solve: (x-3)/x+3/x2=-6/x^2+2x For my solutions, I got -2 and 0, but the problem is, when I plug the numbers back in, I have zero in the denominator which I know you can't have. I'm not sure what I did wrong, or is it just undefined...

Solve: (x+5/x)+(6/x-4)=(-7/x^2-4x) I multiplied the entire function by x and x-4 and after doing that I got down to the quadratic equation x^2+7x-13=0 I did the quadratic and got x=1.525 and -8.525 I feel like I made a mistake because when I plug in both...

Use the following conditions to create a sketch of the function by hand. a. vertical asymptote at x=3 b. x-intercept of 1 and 5 c. f(2)=f(4)=f(6)=3 d. increasing on [0,3) and [5,infinity) e. decreasing on (3,5] f. f(x) is an odd function I don't know how...

Hello and Happy Halloween! Trying to get this problem and could use some help. Find the dimensions of the rectangle with minimum perimeter if its area is 400 square meters. Find the least perimeter. I know that a rectangle has two sides that are equal and...

My question is I^793 I think the answer is just I because it is the only number that can go into it. Is that correct?

The triangle and the trapezoid have the same area. Base b2 is twice the length of base b1. What are the lengths of the bases of the trapezoid? What do you do after you find the area of the triangle? Triangle: base=21 cm, height=6cm Trapezoid: height=6 cm,...

Can you please explain the x-2 and x+1, I'm not sure how you got that.

Oh, these word problems make me feel so dense sometimes. Okay, so I got 54.5 and 51.5 as my demensions. Is that correct?

Hi Sara, You have to create a system of equations. First 3x+4y=1323 Second x+y=400 Now use substitution to solve Can you take it from here?

Thanks, that was a big help :)

oops, my mistake (x-3)/x + 3/(x+2) + 6/(x^2+2x)

oops, my mistake (x-3)/x + 3/(x+2) + -(6/(x^2+2x)) I missed the negative sign

oops, my mistake (x-3)/x + 3/(x+2) = -(6/(x^2+2x)) Sorry, missed the =

Thanks :D

Oh? Now I get it. thanks

I'm not quite sure what you mean. Can you please elaborate

When I plug them in they don't work. am I plugging them in wrong or is it no solution?

So I was correct the answer is i right?

So basically, I have to guess and check. 20 X 20 would be the smallest but is a square. How about 16 X 25 = 82? I would much rather have a mathematical way to go about it.
