B is correct answer
4(3) - 4 = 8
2(3) + 2 = 8
3^2+10^2=c^2
9+100=c^2
109=c^2
Square root both sides and you get:
10.44
(I’m pretty sure I’m right but make sure you double check good lucky
-18x-12=4
Iam not sure if that’s what you want but basically I multiplied the numbers inside the bracket by -6
For x²+bx+c, to complete the square, you add (half of b)²
b=8 in this case, so you add 4², which is 16
x²+8x+16-16-4
y=(x+4)²-20 is the final form.
Answer:
The answer is 2.6. You get this by adding up all the numbers (0,1,2,3,7) and then dividing by the amount of numbers there are (5). The equation would be 0+1+2+3+7=13/5= 2.6
Hope this helps.
