Step-by-step explanation:
6(x + 4) = 20
6x + 24 = 20
6x = 20 - 24
6x = -4
x = -4/6
x = -2/3

Hi There!
Your answer is:
<u>Length = 116</u>
<u>Width = 56</u>
Step-by-step explanation:
L= 4+ 2w
Width=w
perimeter formula
l+l+w+w= perimeter
Subsitute L for 4+2w
(4+2w)+(4+2w) + (w) + (w) = 344
8 +4w+w+w = 344
8+ 6w = 344
-8
6w = 336
/6
w= 56
PLUG BACK IN!
Length = 4+ 2w
Length = 4+ 2(56)
<u>Length = 116</u>
<u>Width = 56</u>

116+116+56+56= 344???
344 = 344 YES

sorry if my answer isn't right
Two complementary angles add up to 90 degrees. Hence, the problem can be set up and solved. Let x represents one angle and 5x represent the angle that is 5 times greater:x + 5x = 90 (simplify)6x = 90 (next divide both sides by 6 to find the value of x [the smaller angle])x = 15 (this is the smaller angle, next subtract 15 from 90 to find the greater angle)90 - 15 = 75 (this is the greater angle which is 5 times that of its complement) <span>90 take away 73...</span>
Answer:
28 sides
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180(n - 2) ← n is the number of sides
Here sum = 4680 , thus
180(n - 2) = 4680 ( divide both sides by 180 )
n - 2 = 26 ( add 2 to both sides )
n = 28
