Volume of the prism is given by: Volume=length×width×height but V=<span>18x^3+5x^2-2x V=x(18x^2+5x-2) V=x(9x-2)(2x+1) Hence the possible expression for the dimensions of the shipping box is x by (9x-2) by (2x+1)</span>
The difference between the 2 different temperatures. The key word difference refers to subtraction. So 18 - ( - 13 ) Subtracting a negative is the same as adding the positive. So 18 + 13 Solve the statement to get: 31
