Give all solutions of the nonlinear system of equations, including those with nonreal complex components. y = x^2 + 4x 2x - y = - 8 -.. Select the correct choice below and, if necessary, fill in the answer box to complete your choice. O A. The solution set is (Type an ordered pair. Type an exact answer, using radicals as needed. Use integers or fractions for any numbers in the expression. Express complex numbers in terms of i. Use a comma to separate answers as needed.) B. There are infinitely many solutions. O C. The system is inconsistent. The solution set is Ø.

Good Day,

The volume of a box is 36x^3+6×^2-72×+30 its length is 3x+5 and uts width is 3x-3 use these to express the height of the box (in terms of x) height =

Help please

Hi there, can you please help me solve this problem? I am very confused and am not sure how to solve it. Thank you! Suppose the area of a rectangle is 18?^3+30?^2+30?+18 and the length is 3?+3. What is the width of the rectangle?
