Answer:
l=48, w=20
Step-by-step explanation:
Let the width of the pool be w feet, then the length will be:

The area of the pool is 960 square feet.
This means that:

Expand and rewrite in standard form to get:




Factor to get:


We discard the negative value because magnitude is positive.
This means


so we know
has roots equal to the cube roots of 1, not including
itself, which are

Any polynomial of the form
is divisible by
if both
and
(this is the polynomial remainder theorem).
This means

But since
is a root to
, it follows that



and since
, we have
so that

From here, notice that if
for some integer
, then


which is to say,
is divisible by
for all
in the given range that are *not* multiples of 3, i.e. the integers
and
for
.
Since 2005 = 668*3 + 1, it follows that there are
integers
such that
.
Finally,
.
if you multiply 18 and 11 you get 198 the you divide it by two and get the final answer of 99
This is a case of counter bore holes. The correct answer is C.
Where:
2 ---- Indicates two holes.
∅1.25 THRU ---- Shows that the holes have a diameter of 1.25 through the material.
Then, there is a counterbore of diameter 2.25 and a depth of 1.00.
Remember you can do anything to an eqautoin as long as you do oit to both sides
-5x=15
try to get 1x by itself
remember
(ax)/a=x when a=a
so
-5x=15
get x
divide both sides by -5
remember to flip sign
(-5x)/(-5)=15/(-5)
x=-3
answer is first one
x=-3
