Answer:
(x - 5)(x + 2)
Step-by-step explanation:
x² - 3x - 10 =
= x² + 2x - 5x - 10
= x(x + 2) - 5(x + 2)
= (x - 5)(x + 2)
Answer:
The area of the pyramid is 360 unit²
Step-by-step explanation:
Given
Base Edge, a = 10
Height, h = 12
Required
Determine the surface area
The surface area of a regular pyramid is calculated as thus;

Substitute values for a and h

Evaluate all squares



Take positive square root of 169



<em>Hence, the area of the pyramid is 360 unit²</em>
