Answer:x=1/24
Step-by-step explanation:
To find 9x(x+6)-(3x+1)^2=1
Open the brackets
9x^2+54x-(3x+1)(3x+1)=1
9x^2+54x-(9x^2+6x+1)=1
9x^2+54x-9x^2-6x-1=1
54x-6x-1=1
Collect like terms
48x=1+1
48x=2
Divide through by 48
x=2/48
x=1/24
Answer: 12 stars
Step-by-step explanation:
First find out the number of stars he gained by scoring goals:
= Number of goals scored * Stars if goal is scored
= 5 * 3
= 15 stars
Then find out the number of stars he is to lose by missing the goal:
= No. of goals missed * stars if goal missed
= 4 * 3/4 stars
= 3 stars
The total number of stars he has are:
= Stars gained - Stars lost
= 15 - 3
= 12 stars
Take the inverse of the power to both sides.
x = y^2/3
Number 1 is a positive change
Number 2 is a negative change. So is the rest. I took this assessment today while at the k12 school and these are the right answers. Hopes this helps!
