Answer:5
Step-by-step explanation:
The perimeter of the rectangle is 20 because 7x2+3x2=20
And 20/4(sides of a square) =5
Answer:
5
perimiter of rectangle is 3+7+7+3 = 20
square x+x+x+x=20
4x=20
x=20/4
x=5
j = 21 and n = 14
we have the equations:
6j + n/3 = 134
j/3 + n = 31
54j + 3n = 1206
j + 3n = 93
53j = 1113
j = 21
(21)/3 + n = 31
7 + n = 31
n = 14
C, 15
i looked it up
x=4
since triangles are proportional by 2:1, then:
16/2=3x-4
8=3x-4
3x=12
Convert mixed fraction to improper fraction.
