Answer:
<
Step-by-step explanation:
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: 25 > -20
Step-by-step explanation
Inequalites is a relationship that support that two values are not equal.
the question states that yvonne owes her sister 25$ that means shes 25$ in debt. since shes owes money to her sister the -$20 is greater.
25> -20
Since the troop made 10 times her then you multiply 950 by 10 and that will give you 9510
First you find the area of the square which is 8²=64 than you find the area of a circle using the formula πr² you get 201.06 and divide it by 4 because you only need the quarter and you get 50.26 the last step is to add the two areas together and you get 64+50.26=114.2
