Hello there!
To do this, we will take the square root from each side
4^2 would be 4
16 would be 4
4 = 4
I hope I helped!

Answer:The second answer there are 3 kids and one adult and the ratio would be 3:1 .
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
x^2 + 7x+ 10. factors out to (x - 2)(x + 5)
C)17
you put the number in order from little to big and the one in the middle is your answer
The general expression is 130 x - 600 and total points scored by the player is 1220
A) Let the number of correctly answered questions be x.
∴ Number of incorrectly answered questions will be 20 - x.
+ 100 points is awarded for each question answered correctly while -30 points is awarded for each question answered incorrectly.
Thus, the general equation becomes
= 100x - (20 - x)(-30)
= 100x +30x - 600
= 130x - 600
Thus the general expression becomes 130 x - 600
B) The player answers 14 questions correctly, thus x = 14
Substituting the value of x =14 in the general equation we get,
= 130(14) - 600
= 1820 - 600
= 1220.
Thus the total points scored by the player will be 1220
