The diagonal of a rectangle is:
d ^ 2 = w ^ 2 + l ^ 2
Where,
w: width
l: long
Substituting values we have:
(l + 2) ^ 2 = (l-7) ^ 2 + l ^ 2
Rewriting we have:
l ^ 2 + 4l + 4 = l ^ 2 -14l + 49 + l ^ 2
l ^ 2 -14l + 49 - 4l - 4 = 0
l ^ 2 -18l + 45 = 0
(l-15) (l-3) = 0
The solutions are:
l = 15
l = 3
The viable solution is:
l = 15
Thus, the width is:
w = l-7
w = 15-7
w = 8
Answer:
the dimensions of the rectangle are:
l = 15
w = 8
Answer:
I think the answer is 200 yards good luck
Answer:
C. 
.
Step-by-step explanation:
The domain of the function refers to the values of 
for which the function is defined.
We can see from the graph that, the function is defined within the interval,
.
When we trace any x-value outside this interval, either up or down we will not meet the function.
Hence, the domain is .
m=24=+(-9,1,3
3
Step-by-step explanation:
Substitute n=3,\pm 1n=3,±1 into 3m-9n=243m−9n=24
Solve for mm in 3m-(-9,1,3)=243m−(−9,1,3)=24
