I NEED HELP QUICK!: At a physics convention, 5 companies set up equal sized square booths in a row along one wall of the convention center. The booths are adjacent to each other and a 3-ft wide walkway surrounds the block of booths on three sides. The total area of the booths and walkway is 1500 ft2. What is the side length of each booth?

Sketch one cycle if the cosine function y=2cos2theta

Which of the statements about the graph of the function y = 2x are true? check all of the boxes that apply. the domain is all real numbers x because the exponent of 2 can be any real number when the x-values increases by 1 unit, the y-value multiplies by 2. the y-intercept is (0, 1). the graph never goes below the x-axis because powers of 2 are never negative. the range is all real numbers.

What is the expression in factored form? -x^2 + 3x + 28 a. (x-7)(x-4) b. -(x-7)(x+4) c. (x+4)(x+7) d. -(x-4)(x+7)
