A composite number is a number that has at least 2 (if you count 1) whole number factor(if you count 1 as a factor)
whole numbers are numbers like 1,2,3,4 but not including -2,-4,-5
factors are numbers that make up another number so
the factors of 6 are 1,2,3 because 1 times 2 times 3=6
3 is not composite because the factors are 1,3
The answer is D there for you the the right answer
Equation: (1/2)(96) = 4x + 4
Solving for x:
0.5 * 96 = 4x + 4
48 = 4x + 4
44 = 4x
x = 11
Hope this helps!! :)
the answer to your question is x^2
Calculating angles are good for Construction without being able to calculate angles corners wouldn't be well a corner since most corners are Right Angles (90 degrees)
The second thing angles are good for is Art Art uses many angles from houses to cities and so on
