Answer:11cm
Step-by-step explanation:
A pentagon has 5 sides
the perimeter Of The pentagon is 55cm
The length of each side Of The regular pentagon is 55/5=11
There length of each side Of The pentagon is 11cm
Answer:
C. x²+3x-28
Step-by-step explanation:
f(x) = x +7
g(x) = x -4
f(x) · g(x) = (x-4)(x+7)
= x²+7x-4x-28
= x²+3x-28
Answer:a
Step-by-step explanation:I know
Answer:
y = 67 degrees
x = 86 degrees
z = 94 degrees
Step-by-step explanation:
This is easy...
38 + 56 = x
94
180 - 94 = 86
86 + 38 + 56 = 180
so x = 86 degrees
___________________
180 - 86 = 94
z = 94
___________________
94 + 19 = 113
180 - 113 = 67
67 + 94 + 19 = 180
so y = 67 degrees
Answer:
Length is w-5
Area = length x width
84 = (w-5)w
84 = w^2 - 5w
0 = w^2 - 5w - 84
0 = ( w - 12 )( w + 7 )
w + 7 = 0 leads to negative measures.
w-12=0 ---> w = 12
width is 12, length is 5 less, or 7
