Step-by-step explanation:
15.

Using the Identity (a + b)(a - b) = (a² - b²) we get
Consider here a = 5c and b = 3 then we will have
.....as required
16.

Here Factorize 8 such that sum up to be 9
∴ 8 × 1 = 8 and 8 + 1 =9
... as required
17.

Here Factorize 21 such that sum up to be -10
∴ -3 × -7 = + 21 and -3 - 7 = - 10
........as required
Therefore

Answer:
It really determines what geometry is.
In simple terms geometry is just shapes.
That’s it really.
You have multiple theorems, postulates, and definitions to help you assist in proofs of theorems or jsut understanding of basic shapes.
The answer is -4. Do you need to know why?
