The answer is 36+4x u want me to explain?
Sub -3 for x
f(-3)=-(-3)^2-5
f(-3)=-(9)-5
f(-3)=-9-5
f(-3)=-14
Brand X cost: $4.50

Answer:
Step-by-step explanation:
The formula of an area of a rectange:
<em>w</em><em> - width</em>
<em>l</em><em> - length</em>
<em />
We have:
Substitute:
<em>use a² - b² = (a - b)(a + b)</em>
Answer:
A
Step-by-step explanation:
The equation of a line in point- slope form is
y - b = m(x - a)
where m is the slope and (a, b) a point on the line
y - 3 = 4(x + 8) ← is in point- slope form
with slope m = 4 and (a, b) = (- 8, 3) → A
