This involvea factoring the polynomial into binomials and solving.
So make it (3x+1)(x-7)
X equals 7 and -1/3
If using the radius, you would multiply the radius by 2*pi, to calculate the circumference, which should be the same as the answer i got.
Answer:
x/6 = 4/5
x(5) = 6(4)
5x=24
x=24/5
Let me know if this helps!
Answer:
x = -1
Step-by-step explanation:
-4(3x-7) =40
Divide each side by -4
-4(3x-7)/-4 =40/-4
3x-7 = -10
Add 7 to each side
3x-7+7 = -10+7
3x = -3
Divide each side by 3
3x/3 = -3/3
x = -1
