Step-by-step explanation:
L= length
w= width= L-3
A= area= 238 ft^2
LENGTH
Area Formula
A= LW
substitute w value
238= (L)(L- 3)
multiply L by parentheses
238= L^2 - 3L
subtract 238 from both sides
0= L^2 - 3L - 238
factor
0= (L + 14)(L - 17)
set each parentheses equal to 0
0= L + 14
-14= L
OR
0= L - 17
17 ft= L
*Since the measure of a rectangle would not be negative, L= 17 ft
WIDTH
w= L - 3
w= 17 - 3
w= 14 ft
ANSWER: Length= 17 ft; Width= 14 ft
Hope this helps! :)
That's a very interesting question.
Here's the way I thought about it, and the answer I came up with
while avoiding the need to define and count every possible outcome:
-- There are (2 x 2 x 2 x 2) = 16 possible outcomes of 4 flips.
-- There are several different ways to get 1 heads and 3 tails.
-- There are several different ways to get 2 heads and 2 tails.
-- There are several different ways to get 3 heads and 1 tails.
-- But there's only one way to get heads all 4 times,
and there's only one way to get tails all 4 times.
-- So there are 2 ways for all 4 flips to produce the same face.
The probability of that is 2/16 = 1/8 = 12.5% , and I'm saying
that this is the least probable result of 4 flips.
It’s c because ur the over the 2 pounds
Answer:
Step-by-step explanation:
Start by extracting the numerical common factors. Notice that 4 is a factor in all coefficients. Therefore:
Now study the trinomial that is left, and look for numerical coefficients that multiplied give as result the last coefficient in the trinomial (-18) and when combined give you the coefficient in the linear term (-7). Notice that the coefficient -18 can be created by the product of (-9) times (2), and that these numbers combined give you exactly "-7" which is your middle coefficient. Therefore use them to factor out the trinomial:
Therefore, the full factoring of the initial trinomial is written as:
