All real numbers except -4 and 9.
The domain of an expression is the range of all values for which the expression is defined. Looking at the expression, it will legal everywhere except when a^2 - 5a - 36 is equal to 0. Since that's a quadratic equation, we can use the quadratic formula to find where its value is 0, giving -4 and 9.
Therefore the domain of the expression is, All real numbers except -4 and 9.
Pays $94
brushes = $40
94 - 40 = 54
54 ÷ 6 = 9
each can of paint costs $9
Answer:

1 2
------- = --------
4a 3
cross multiply
2(4a) = 1 * 3
8a = 3
a = 3/8 or a = 3 over 8
answer
<span>3 over 8</span>
A suitable matrix calculation tells you
(x, y, z) = (-8, -1, -3).
