Step-by-step explanation:
So, one factor is (x - 1). After division, or guest --> f(x)=(x+1)(x2+6x+8) Find 2 numbers knowing the sum (6) and the product (8). They are 2 and 4.
The value of x that will result for the rational expression to be undefined will be the values that will give 0 value for the denominator.
A. 7
<span>2(7)^2 -32 = 66
</span>
<span>B. 4
</span>2(4)^2 -32 = 0 <span>-------> undefined</span>
C. 2
2(2)^2 -32 = -24
<span>D. -2
</span>2(-2)^2 -32 = -24
<span>E. -4
</span>2(-4)^2 -32 = 0 -------> undefined
F. -7
2(-7)^2 -32 = 66
The numbers that are irrational are B. √72 and D.√23.
<h3>What are irrational numbers?</h3>
Irrational numbers are those that have infinite numbers after the decimal. These numbers are also none repeating.
When the above are solved:
√25 = 5
√144 = 12
√23 = 4.79583152331...
√72 = 8.48528137424...
The only two numbers with non-repeating and infinite numbers are √72 and √23.

Answer:
Step-by-step explanation:
Area of the field = pi * r^2
r = 230/2 = 115
Area of the field = 3.14 * 115^2 = 41526.5 square feet.
Number of bags = 41526.5/400 = 103.82 bags
Answer:
d.
Step-by-step explanation:
triangle - 6 x 4 = 24 24 divided by 2 = 12
rectangle - 10 x 6 = 60
semi circle - area of circle = pi r^2 28 divided by 2 = 14
12 + 60 + 14 = 86
