Answer:
4(x-1/2)^2+0
Step-by-step explanation:
I used the formula (b/2)^2
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
We have the following equation:
-1/3m - 7 = 5
From here, we must clear the value of m.
We have then:
-1/3m = 5 + 7
-1/3m = 12
1/3m = -12
m = - (3) * (12)
m = -36
Answer:
The value of m is:
m = -36
