The unknown term that is being asked for this item is an ANGLE. This defined geometric term is formed when two rays combined at a common point usually called the vertex. The combining rays are called sides. The types of angles are acute, right, obtuse, straight, reflex, etc depending on its measure.
The answer is cr=ds to the question
Answer:
13×36
Step-by-step explanation:
the angle wants you to multiply 13×36
Answer: 
Step-by-step explanation:
The perimeter of a rectangle can be calcualated with this formula:
Where "l" is the lenght and "h" is the height.
The area of a rectangle can be found with this formula:
Where "l" is the lenght and "h" is the height.
In this case we know that:
Therfore, we can susbsitute them into and solve for "h" in order to find its value:
Find two number whose sum is 3 and whose product is -40. These are -5 and 8. Then, factorizing, we get:
The positive value is the height. Then:
Since the length is 3 centimeters greater than its height, we get that this is: Then:
Substituting values into , we get that the perimeter is:
Answer:
246 physics books
186 biology books
Step-by-step explanation:
1) there are 432 total books
2) there are 60 more physics books than biology books
3) 432 - 60 = 372
4) 372 divided by 2 = 186
5) 432 - 186 = 246
Check:
246 + 186 = 432
246 - 186 = 60
hope this helped :)
