Step-by-step explanation:
Define ...
z = 3x+2
Substitute for that expression in the given quadratic:
z^2 +7z -8 = 0 . . . . . . your equivalent quadratic
_____
This equation is easily solved by factoring:
(z +8)(z -1) = 0
z = -8 or +1
Then x can be found from z:
(z -2)/3 = x
(-8 -2)/3 = x = -10/3
(+1 -2)/3 = x = -1/3
Step-by-step explanation:

Area formula:
3.14*radius*radius
Substitute in numbers you already know (radius is half the diameter):
3.14*(6/2)*(6/2)
=3.14*9
=28.26
The area is 28.26 square meters.
Circumference formula:
3.14*diameter
Substitute in numbers you know:
3.14*6
=18.84
The circumference is 18.84 meters.
Hope this helped!
