Total number of hours=18 hrs
Number of engineers=3
So divide number of hours by number of engineers.
18/3=6 hours
Answer: Option A 6
6x^4-17x^3-7x^2+13x=3
6x^4-17x^3-7x^2+13x-3=3-3
6x^4-17x^3-7x^2+13x-3=0
y=6x^4-17x^3-7x^2+13x-3
y=0
The solutions are: x=-1, 1/2, 1/3 and 3
Answer:
Step-by-step explanation:
A(-5,-2),B(-2,-2), C(-5,2)
find distance first:d=√(x2-x1)^2+(y^2-y1^2)
AB: 3
BC: 5
AC: 4
perimeter of triangle=3+5+4=12
compliment angle=90
90+34=124
5x+17+x+19=180
x=24
