The answer is A
(although I cannot see the rest of the answers)
Answer:
A
Step-by-step explanation:
An excluded value is any value of x that makes the denominator of the rational expression zero as this would make the expression undefined.
For expression A
The denominator will be zero when x² - 4 = 0
x² - 4 is a difference of squares, thus
(x - 2)(x + 2) = 0
x - 2 = 0 ⇒ x = 2
x + 2 = 0 ⇒ x = - 2
The excluded values of x are x = ± 2 ⇒ A
Answer:
48. Expression 1a: 1.05($16x)
Expression 2a: 1.07($18x)
Expression 1b: 0.9 × [1.05($16x)]
Expression 2b: [1.07($18x)] - $20
0.9 × [1.05($16 × 15)]
0.9 × [1.05($240)]
0.9 × $252
$226.80
[1.07($18 × 15)] - $20
[1.07($270)] - $20
$288.90 - $20
$268.90
$226.80 + $268.90 = $495.70
Answer: $495.70
47. 1 = 30
2.5 = 75
30 × 75 = 2,250
15^2 = 225
Pi × 225 = 706.86
706.86 + 2,250 = 2,956.86
Answer: 2,956.86 square feet
30 × Pi = 94.25
75 × 2 = 150
94.25 + 150 = 244.25
Answer: 244.25 feet
So what you do is make a fraction with the conversation between miles and km with km on the bottom to cancel out the units and multiply the fraction by the amount of km
5km (.62miles/1km) = 3.1 miles
