Question

uestion Solve the problem. The perimeter of a rectangular lot of land is 436 ft. This includes an easement ofx feet of uniform width width of the easement. Select one: Not yet inside the lot on which no building can be done. If the buildable area is 122 ft by 60 f, determine the answered Points out of 6.25 P Flag question a‘ 9 feet b. 18 feet G.4.5 feet d, 7 feet O O Previous page Next page

Answer 1

the buildable are is 122 ft by 60 ft so that the dimension of the plot is 122 + 2 x ft by 60 + 2 x ft since the perimeter is 2 * length + 2 * width , hence 2 (122 + 2 x) + 2 (60 + 2 x) = 436 04 , 244 + 4 x + 120 + 4x = 436 or , 8 x = 436 - 364 = 72 so that x = 72 /8 = 9 ft the 1st option is the correct answer the real part of complex number 4/7 is 4/7 and the imaginary part is O. option a is the correct answer we have j^2 - 4 j + n = (j^2 - 4 j + 4) + n - 4 = (j - 2)^2 + n - 4 hence n - 4 = 0 and n = 4 option a is the correct answer (3z - 18)^2 + 59 = 14 - 59 = - 45 then 3 z - 18 = plusminus squareroot (- 45) = plusminus 3 i squareroot 5 then 3 z = 18 plusminus squareroot so that z = 6 plusminus 3 i squareroot 5 option a is the correct answer we have - 5y^2 = 5 + 7 y or 5y^2 + 7y + 5 = 0 or (y squareroot 5)^2 + 2 *
