Answer:
The measure of <em>x</em> is:
9 inches
Step-by-step explanation:
Perimeter = x + 2(x-4)
perimeter = 19 inches
then:
19 = x + 2(x-4)
19 = x + (2*x) + (2*-4)
19 = x + 2x - 8
19 = 3x - 8
19 + 8 = 3x
27 = 3x
27/3 = x
x = 9 inches.
<span>-x^2 - 4x when x = -3
-(-3)^2 -4(-3)
= - 9 + 12
= 3
answer is </span><span>B. 3 </span>
