Answer:
C. 12cm
Step-by-step explanation:
The equation for the perimeter of the rectangle is ...
P = 2(L+W)
34 = 2(n +m)
Solving for m, we get
m = 17 -n . . . . . . . divide by 2, subtract n
__
The Pythagorean theorem gives the relationship between the sides and the hypotenuse
m^2 +n^2 = (n+1)^2
(17 -n)^2 +n^2 = (n +1)^2 . . . . . . substitute for m
289 -34n +n^2 +n^2 = n^2 +2n +1 . . . . eliminate parentheses
n^2 -36n +288 = 0 . . . . . . . put in standard form
(n -12)(n -24) = 0 . . . . . . . . . factor
n = 12 . . . . . . . . . . n=24 is an extraneous solution here
The value of n is 12 cm.
Answer:
<h2>
k = 31/9</h2><h2>
b = 12</h2>
Step-by-step explanation:
<u>k - 4</u> = 3
9
k/9 = 3(9) + 4
k = 31/9
k = 31/9
<u>8 + b </u> = -5
-4
8 + b = -5 (-4)
8 + b = 20
b = 20 - 8
b = 12
the answers is
1 Inch = 4 Feet
Here is the explanation -
the side of square = 12
length of Ground - 48
ratio of length = 12 /48
= 1/4
1 : 4
