Answer:
90% sure it's 5/7
Step-by-step explanation:
Answer:
the answer is the option B
b(x) has the highest value in years; b(x) has the highest value in years
Step-by-step explanation:
x------> the time in years
b(x)----> the value in dollars of a saving account
c(x)----> the value in dollars of another account
we know that
Step 1
Find the value of each account for
so
----> b(x) has the highest value in years
Step 2
Find the value of each account for
so
----> b(x) has the highest value in years
Angles are vertical opposite so they would be equal.
2x + 2 = 3x - 52
3x - 2x = 52 + 2
x = 54
In short, Your Answer would be 54
Hope this helps!
To be a perfect square this condition must be applied b^2 -4ac>=0
where a is coefficient of x^2 and b is coefficient of x and c is the last term
so in this equation
a=1 ; b = ? ; c= 81
b^2 -4ac >=0
b^2 -4(1)(81)>=0
b^2 >= 324
so b= 18
