Answer:
22.2 ft²
Step-by-step explanation:
The area (A) of a sector is calculated as
A = area of circle × fraction of circle
= πr² × 
= π × 7.13² × 
= 
≈ 22.2 ft² ( nearest tenth )
The answer is A.
If a redundant conclusion is reached in basic algebra this states that the variable holds all possible real values.
If you algebraically solve Kendra's you do achieve the true statement 5 = 5 (leaving out D). And if you test any value of x for the equation it does hold true (getting rid of B).
Hopefully this makes sense.
<span>Many simple inequalities can be solved by adding, subtracting, multiplying or dividing both sides until you are left with the variable on its own.But these things will change direction of the inequality: ...<span>Don't multiply or divide by a variable (unless you know it is always positive or always negative)</span></span>

Answer:
n = -5/13
Step-by-step explanation:
-8+4(1+5n)=-6n-14 (from PEDMAS, expand parenthesis first)
-8+1(4) +5n(4)=-6n-14
-8+4 +20n=-6n-14
-4 + 20n = -6n -14 (add 6n to both sides)
-4 + 20n + 6n = -14
-4 + 26n = -14 (add 4 to both sides)
26n = -14 + 4
26n = -10 (divide both sides by 26)
n = -10/26 = -5/13
