Answer:
346
Step-by-step explanation:
6z2+2z+10
(6 x 3)^2 + 2 x 3 + 10
18^2 + 12 + 10
324 + 22
346
If you would like to know the solution to the equation (x - 2) * (x + 5) = 18, you can calculate this using the following steps:
(x - 2) * (x + 5<span>) = 18
</span>x^2 + 5x - 2x - 10 = 18
x^2 + 3x - 28 = 0
(x + 7) * (x - 4) = 0
1. x = - 7
2. x = 4
The correct result would be x = - 7.

Answer:
The set
Step-by-step explanation:
We separate the left and right side of the equation, to create two new equations:
(1)
(2).
and then to solve Tanisha's original equation, we find the solution to the system that we got above.
The first step in solving the above system of equations is to take the value for 
from equation(1), and substitute it into equation(2) which gives us:
which is the same equation that Tanisha set out to solve.
