(1-4) over (5-1)
-3 over 4
Answer: The domain is 3/7, -6, and 4.
Step-by-step explanation:
In the case of rational expressions, we can input any value except for those that make the denominator equal to 0 (since division by 0 is undefined). In other words, the domain of a rational expression includes all real numbers except for those that make its denominator zero.
Answer:
(x-3) (x+5)
Step-by-step explanation:
After determining that there was no GCF, I just used the trial an error method using the factors of 15. For small numbers like the one provided, it is pretty fast and effective.
Draw a rectangle. If the length is 3 inches longer than its width, we can write the width as "w" and the length as the width + 3
Area is (width)(Length) = (width)(width+3)
W

A = (w+3)(w)
A = w2 + 3w = 108.
(Problem states that area is 108 sq in)
Need to solve this quadratic equation
w2 + 3y - 108 = 0
Factor:
(w - 9) (w + 12) = 0
So
w - 9 = 0. or. w + 12 = 0
Solve these and get
w = 9. or. w = -12
Only one that makes sense in real life is the poitive one.
So the dimensions are
Width = 9 inches
Length = 12 inches
Answer:
Part A:24140 PartB: 16865
Step-by-step explanation:
multiply the total number of people by the decimal form of the percentage (move decimal left two places)
71000*.34=24140
71000*.425=30175
then to find the other number you must add the two before then subtract from the total
24140+30175=54135
71000-54135=16865
