Just has to be greater than or equal to 0... w and t can never be negative since taking the square root of a negative number yields an imaginary number which would mean imaginary current. Also the question states that w can't be zero but if T is zero than the current will be zero.
What is the area of trapezoid ABCD ?
The "area of trapezoid ABCD ?" = <u>9 units²</u>
First write the factors of 9:
9, 18, 27, 36, 45
Then look for ones that are greater than 20:
27, 36, 45
Hope this helps :)
the error was that you did not use the distributive property in 4(x-2)
Volume = Length * Breadth * Height
Volume = 15 * 8 *3 = 360
Volume = 360 Cubic meters.
