Answer:
A) Quantity x minus 5 over quantity x plus 1, where x≠-1 and x≠-9
Step-by-step explanation:
Simplifying the numerator first:
x² + 4x - 45 using the quadratic formula you get;
(x - 5)(x + 9)
Then simplifying the denominator x² + 10x + 9 using a quadratic formula you get;
(x + 1)(x + 9)
Dividing the numerator and denominator now gives;
Cancelling (x + 9) throughout leaves you with;
The only restrictions here is if x = 1 and 9 which will give an undefined answer.
Answer:
Option c. 30,000
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent an inverse variation if it can be expressed in the form 
or 
Let
y ----> safe load in pounds
x ----> length in feet of a horizontal beam
we have
For 
Remember that
substitute
D is 4/4, or just simply 1
Answer:
15 yards, 45 feet and 540 inches are equal.
Step-by-step explanation:
To know if the measurements are equal, we first need to convert all the measures to the same unit. In this case, I will convert them all to feet.
a.6 feet
b.15 yards ≈ 45 feet
c.45 feet
d.600 inches ≈ 50 feet
e. 12 feet
f. 540 inches ≈ 45 feet
Therefore, b, c and f are equal.
