Answer:
Step-by-step explanation:
x2 - 6x = - 25
Rearrange the equation and let it be equal to 0
x2 - 6x +25 = 0
Using the Almighty formula
x =( -(-6) + √9)/2 or (-(-6) - √9)/2
x =4.5 or-1.5
x = 4.5
b=16 , First you multiply 30 by 2 to see what sum you need for the numerator. Then you subtract the 60 that you get by the 12 and get 48. So 3 multiplied by b should give you 48. So you just divide 48 by 3 and get 16.
