Thirteen is about what percent of 20

13 is what percent of 20? = 65.

13: 20*100 =

(13*100): 20 =

1300: 20 = 65

Percentage solution with steps:

Step 1: We make the assumption that 20 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x.

Step 3: From step 1, it follows that $100\%=20$100%=20.

Step 4: In the same vein, $x\%=13$x%=13.

Step 5: This gives us a pair of simple equations:

Answer to your question: a. the fundamental theorem of algebra tells you that the equation will have two complex roots since the degree of the polynomial is 2. the roots are ​ x=1±i7√2 .number of roots=degree of polynomialhere, degree of polynomial is 2 so number of roots will be 2.hope it *_*
