Answer:
B.) 166
Step-by-step explanation:
10 x 2 = 20
12 x 10 = 120
13 x 2 = 26
20 + 120 + 26 = 166
Number: n
square of number: n^2
sum of n and n^2 is n+n^2=20
Rewriting this equation, we get n^2+n-20=0 = (n+5)(n-4) = 0
Then n+5=0 and n-4=0, so n = -5 and n = 4.
You must check both results. It could happen that both are correct, or that only one is correct.
Answer:
answer = $144.40
Step-by-step explanation:
34/100 × $424.71
