Answer: 110 square cm
=======================================================
Explanation:
All sides of a regular polygon are the same length. So the bottom side is also 8 cm.
Draw lines from the center to each vertex of the pentagon. Five triangles form. Each triangle has a base of 8 and a height of 5.5 (since all five triangles are congruent)
area of one triangle = 0.5*base*height = 0.5*8*5.5 = 22
area of five triangles = 5*(area of one triangle) = 5*22 = 110
Answer:
The solution of the given equations are (3,2).
Step-by-step explanation:
Given equations are :
3d−e=7 ...(1)
d+e=5 ...(2)
Add equations (1) and (2) we get :
3d-e+d+e=7+5
4d = 12
d = 3
Put the value of d in equation (2).
3+e=5
e = 2
So, the value of d = 3 and e = 2. Solution of the given equations are (3,2).
Answer:
84 yards (don't forget to label, as my friend failed a test because of it!)
Hope this helps
Step-by-step explanation:
The total perimeter of the field is 358
The are length and widths...
the length is 95
but since there are two lengths...
its 95*2 which is 190
358-190=168
Since there are two widths...
168/2= 84
Answer:
x^4+8x^3+18x-27=0
Step-by-step explanation:
In a equation of the form

you have roots in x=a and x=b, and multiplicity of n and m respectively.
Hence, the equation is

by expanding the factors you have

Answer:
0.23
Step-by-step explanation:
23 percent is 23/100, so to find the decimal, you move the point two places to the left.
