Step-by-step explanation:
This is not a difficult question and I will help you solve it :)
When calculating 1/10 from 40, what we have to do is this:
(1/10) * 40 = 4
This means that we have to multiply 40 by 1 and divide by 10 :)
So the answer in this case is 4.
Every difference of squares problem can be factored as follows: a2 – b2 = (a + b)(a – b) or (a – b)(a + b). So, all you need to do to factor these types of problems is to determine what numbers squares will produce the desired results. Step 3: Determine if the remaining factors can be factored any further.
Width of the rectangle is x + 3 in
Step-by-step explanation:
- Step 1: Given area of the rectangle = 3x² + 9x in². Length = 3x in. Find width.
Area = length × width
3x² + 9x = 3x × width
∴ Width = 3x² + 9x/3x = x + 3 in
