Use the distributive formula
a(b - c) = ab - ac
a(b - c) = ab - ac
Simplify: √(x^2-6x+9) if x<3

Answer:
Perimeter: 52 Area: 181-16i?
Step-by-step explanation:
<u>Perimeter</u>
The formula for perimeter is 2l+2w, so you plug in the binomials they give you:
2(11-4i)+2(15+4i)
expand:
22-8i+30+8i
combine like terms (which cancels out 8i and -8i):
22+30=52
<u>Area</u>
"i" is not a real number and thus should not be part of the area here, meaning this answer as it is is wrong and I don't know how one would change that.
Here's what I did to get 181-16i, in any case:
The formula for area is l*w, so I plugged in the numbers:
(11-4i)(15+4i)
expanded:
165+44i-60i-16i*i
and combined like terms:
181-16i
*i is , so
=-1 and -1*-16=16.
Answer:
The graph approaches –3 as x approaches infinity. Option a is correct.
Step-by-step explanation:
The given function is
We have to find value of function as x approaches infinity. Take limit both sides as x approaches to infinity.
Taking x common from the denominator.
Cancel out common factor x.
Apply limits.
Therefore the graph approaches –3 as x approaches infinity.
