All right, we're given the area of this parallelogram, and we're given the length of the base, and we want to find its height.
00:10
And we know that the area of a parallelogram equals base times height.
00:14
So then to find the height, we could take the area and divide it by the base.
00:18
So we can use synthetic division for that.
00:21
We're going to take our area and divide it by our base.
00:26
So we'll put negative 5 in the box for synthetic division, and the coefficients of the area in a row, 1, x to the 3 .5 .5.
00:33
4, 0x cubed, negative 23x squared, 9x, and negative 5.
00:40
You always need zeros for the terms that are missing.
00:43
Okay, we bring down the first number, 1.
00:46
Multiply it by the number in the box, we get negative 5, write that in the next position, and add the column, we have negative 5...
