12x15=18(3x+4)
180=54x+72
-72 -72
108=54x
/54 /54
2=x
X=2 the other person is a d0uche for answering like that so I answered instead of them
26 units is the answers for this questions. To find the perimeter, put a slash in each square. The only squares that will get 2 slashes is the corners
Answer:
<em>l</em> = 1 5/16
w = 1/16
A = 21/16 x 1/16 = 21/256
Step-by-step explanation:
Perimeter = 11/4
<em>l</em> = length
w = <em>l</em> - 5/4
2<em>l</em> + 2(<em>l</em> - 5/4) = 11/4
2<em>l</em> + 2<em>l</em> - -5/2 = 1/4
multiply each side by 4
8<em>l</em> + 8<em>l </em>- 10 = 11<em> </em>
16<em>l</em> = 21
<em>l</em> = 21/16 or 1 5/16
width = 21/16 - 20/16 = 1/16
I divided 315 by any random number and chose the one that gave me a whole number
So I got

x
Answer:
Step-by-step explanation:
23(9x-6) = 4x +10
207x - 138 = 4x +10
203x = 148
x = 148/203
or
3(9x-6) = 4x +10
27x -18 = 4x + 10
27x - 4x = 10 + 18
23x = 28
x= 28/23
