<span>6x^2+7x+2=0
(3x+2)(2x+1)=0
3x+2 = 0; x = -2/3
2x+1 = 0; x = -1/2
answer
x = -1/2 and x = -2/3</span>
Hello,
The answer should be "4".
Reason:
Since Logan takes 12 hours and Marcus takes 16 i just subtract 16 and 12.
16-14=4
=4 hours
If you need anymore help feel free to ask me!
Hope this helps!

① 15² = 4² + 2(32) x
225 = 16 + 64x
-64x = 16 - 225
-64x = -209
x = 209/64
② 105 = 45 + 5x
-5x = 45 - 105
-5x = -60
x = 60/5
x = 12
Answer:
-3 is the other solution.
Step-by-step explanation:
As, is One of the solutions of the equations , So, it should satisfy the equation.
Putting in equation 5 + bx + 12 = 0 ,
We get,
5×× + b× + 12 = 0.
5× + + 12 = 0.
After solving , 16 - 4b + 60 = 0.
4b = 76
b = 19.
So, the equation is 5 + 19x + 12 = 0.
After factorizing , 5 + 15x + 4x + 12 = 0.
5x(x+3) + 4(x+3) = 0
(5x+4)(x+3) = 0
Clearly the roots of the equation are -3 and .
So, the other solution is -3.
