Greetings and salutations!

I have some questions that I can't figure out.

1

the perimeter of a rectangular yard is 290 feet. If its length is 25 feet greater than its width, what are the dimensions of the yard?

Set one side to be x and the other becomes x+25..
2

What is the equation in standard form of the line through (4,1) and (-2,3)?

You want to find the inclination of the line. That is given by:

.

now we have

Now you want to find the constant...ill leave that part to you

3

Write in simplest form without negative exponents.

(2/3)^-2(4/5)^-1

[I think i have an answer to this one:

(2/3)^-2(4/5)^-1=(2^-2/3^-2)(5/4)=(2^-2*{1/3}^-2)(5/4)=({1/2}9)(5/4)=(9/2)(5/4)=48/8=6]

Im not sure how this is menth to be cause I believe there are som bracetts missing.

Thanks
