Answer:
-60
Step-by-step explanation:
-42+3×(-6)
-42-(3×6)
-42-18

Answer:
13in
Step-by-step explanation:
To find the diagonal we use the Pythagorean Theorem:
52+122=x2 where x = hypotenuse
25+144=x2 or x=13in
The perimeter would be 39 feet. The area would be 360 feet. I'm not sure which will be appropriate for this question (you decide).
Answer:
6 hours
Step-by-step explanation:
180 divided by 30 = 6
Complexes with a coordination number 4 mostly adopt tetrahedral and squar planar geometries.
<h3>What is geometry?</h3>
- Geometry is a subfield of mathematics that examines the measurement and relationships of surfaces, solids, solid surfaces, angles, and points.
- Ge and metria, two Greek terms that signify "measuring," are the origin of the word geometry. The foundation of geometry has been the method of geometry devised by the Ancient Greeks for more than 2000 years.
- The calculation of a triangle's angles is a geometry example.
- Plane geometry, solid geometry, and spherical geometry are the three most popular types of geometry.
