Step-by-step explanation:
12g=12(2/3g-1)+ 11
12g=24/3g-12+11
12g-24/3g=-1
12g-8g=-1
4g=-1
g=-1/4
Let me work it out real quick i’am not sure yet
28.27 is the area of the circle with a diameter of 6
58r=70
r=35/29
r≈1.2069
So the rate was about 1.21 or if you prefer about 20.7%
Answer:
4ab
Step-by-step explanation:
(a+b)^2-(a-b)^2
=a^2 + 2ab + b^2 -(a^2 - 2ab +b^2)
=a^2 + 2ab + b^2 - a^2 + 2ab - b^2
=2ab + 2ab
=4ab
