The answer is 31.18 because you do base 1 plus base 2 divided by 2 then times the height.
The last one
You’re completing the square here so you have to find (1/2b)^2. In this case it’s 1. So you have to add 1 to both sides. Then you have to solve for it
It becomes
(x-1)^2 = -7
Then you have to find the square root
(x-1) = √-7
x-1 = √7 √-1
x-1= ± i √7
x= 1 ±i √7
That’s your answer and d is the only one that matches with it
30(x) - 65 = 565, X represents the amount of paychecks he has to cash in and the -65 is the money he has to pay back first.
