What are the domain restrictions of a + 1 / a^2-5a-36?

velikii [3]

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.

The formula for a trapezoid relates the area A, the two bases, a and b, and the height, h.

saveliy_v [14]

I'm assuming the original equation is $A= \frac{h(a+b)}{2}$
Step 1: Multiply both sides by 2 to eliminate the denominator
Step 2: divide by h
Step 3: subtract a
$b= \frac{2A}{h} -a$
