A composite number is a number that's not prime. A prime number is a number who only has 2 factors (1 and itself). A composite number has multiple factors.
For example;
7 is prime, as the factors of 7 are only 1&7.
14 is composite, as there are 4 factors (more than 2); 1&14, 2&7.
91 is composite, as it has the following factor pairs; 1&91, 7&13.
139 only has 1&19, making it prime.
13 only has 1&13, making it prime.
29 only has 1&13, making it prime.
Your answer is A.) 91.
I hope this helps!
All sides of as quaer are equal
4 sides to a square
therefor perimiter=4 times 1 side
if 1 side=4' then 4 sides=4 times 4'=16'
answer is 16'
125000
Explanation:
(x= 1% of annual income)
15x+14x=36250
29x=36250
divide each side by 29
x=1250
1250x100=125000
(1/4)*(4*x+15) = 24 // - 24
(1/4)*(4*x+15)-24 = 0
1/4*(4*x+15)-24 = 0
1/4*(4*x+15)-24 = 0
x-81/4 = 0
x-81/4 = 0
x-81/4 = 0 // + 81/4
x = 81/4
x = 81/4
