Let's look at the equation for a perimeter:
P=Width * Length
We also have another equation for P:
P
134ft
We know Width(29ft), so let's substitute:
(29)(Length)
134
If we isolate Length, by dividing 134/29, we get:
Length
which simplifies to about 4.6207
Therefore, I believe all possible values for the Length of the deck would be:
(
, ∞)
Or: {x(x≥
)}
Hopefully this helps!
So based on your diagram the following are the answers to your questions:
<span>(a) Use an equation to express the length y of the building in terms of the width x.
</span>- y(x) = 600/x
(b) If the walls cost $100 per running foot, use an equation to express the cost C of the <span>walls in terms of the width x.
- the answer is 6

Answer:
(a) The distance from -14 to 0 on a number line. The answer is 14.
Step-by-step explanation:
If you put "-14" in the problem statement in place of the word "number," you will find it substantially matches the wording of answer choice A. |-14| means ...
The distance from -14 to 0 on a number line. The answer is 14.
To factor by a binomial, I like to use synthetic division (You can use long division but it is more work).
We are actually given a binomial because if -2 is a zero, the binomial is represented by (x- (-2)) or (x+2)
To use synthetic division,
-2 | 1 2 -9 -18
-2 0 18
____________
1 0 -9 0
Therefore, you know the constants of the equation which is equal to
1x^2 +0x -9x +0
x^2-9x
The full equation is equal to (x+2)(x^2-9x)
Its the same as dividing by 2 rather than multiplying by 1/2. I was tipd its less work:) Hope this Helps!
