Answer:
$163.5
Step-by-step explanation:
$150 - ($10.5 + $6.75) + $30. 75 = $163.5
The formula for the area of a rectangle is length times width, or A=l·w
The Area A=256
The width is w
The lenght is given as 6 feet less than 4 times its width, or in math language this is l=4w-6
Let's go back to the formula
A=l·w ⇒ 256=(4w-6)·w
simplify ⇒ 256=4w²-6w
put everything on the same side and set the equation equal to zero
⇒ 4w²-6w-256=0
Solve for w using quadratic formula
You are going to get two answers after using the quadratic formula: one positive and one negative. Just remember it doesn't make sense to get a negative answer if we are talking about width, so use the positive answer only
w≈8.7851 units

The choices are the below that can be found elsewhere:
<span>a. { 1, 2, 4 }
b. { 0, 3, 5, 8 }
c. { 0, 1, 2, 3, 4, 5, 8 }
d. { ( 0, 2 ), ( 3, 1 ), ( 5, 2 ), ( 8, 4 ) }
</span>
The answer is B <span>because the domain is just the X-values of the ordered pairs and you cant repeat them.</span>
Puppies : Adults = 1 : 4
Total parts = 1 + 4 = 5
5 parts = 100 dogs
1 part = 100 ÷ 5 = 20 dogs
Answer: 20 puppies
