Answer:
35
Step-by-step explanation:
Since i=-1, we can rewrite the equation as 3-[4(-1)} multiplied by 6+(-1). Since
4 x-1=, 3-(-4)=7. 6-1=5, and 7x5=35.
12 inches=1 foot
There are 72 or 12 x 6 inches in a foot which means 6 feet.
There are 2 inches remaining so there are 6 2/12 or 6 1/6 ft in 74 inches.
The common factor is 2 so: 2(4x+3) is the answer
