( - 8 + b )( - 4 - 3 ) = 0;
( - 8 + b )( - 7 ) = 0 ;
-8 + b = 0;
b = 8.
35 cm
using the formula a=1/2(b)(h), we can plug in 14 for b and 5 for h. This gives us 70, and when we multiply by 1/2 it leaves 35 cm.

Answer:
Step-by-step explanation:
6x - 2y = -4
y= 3x + 2
We see that y = 3x + 2 so we can use that value of Y everytime we see i in the other equation.
6x - 2(3x +2) = -4
Now usually we'd we simply solve for X.
6x - 6x -4 = -4
This clearly does not work as we cannot get rid of X
Therefore, this system of equations has no solution we can find through substitution
