4/12 in simplest form is 1/3
4/12 ÷ 4/4 = 1/3
The square root of negative four is 2
(-2,3) to (2,-3)
6^2 + 4^2 = c^2
c = 7.21
————
(-2,3) to (1,5)
2^2 + 3^2 = c^2
c = 3.61
————
3.61 * 7.21 = approx. 26.03
The area is 26.03un^2
Step-by-step explanation:

Answer:
14
Step-by-step explanation:
if b=4 and a=2, then you substitute both those values into the equation, turning (4b - a) into (4*4 - 2), then you use order of operations, meaning you multiply the 4 times the 4, which turns it into 16-2, and then subtract 2 to finally reach your answer of 14.
