3 - 6a = 9 - 6a.....subtract 9 from both sides
3 - 9 - 6a = 9 - 9 - 6a...combine like terms
- 6 - 6a = -6a ....add 6a to both sides
-6 - 6a + 6a = - 6a + 6a...combine like terms
-6 = 0...incorrect....means there is no solution to this
It is a function. Every x value is different.
There are 6 sides and each side is 4mm long:
As = 6*(L*W) = 6*(4*4) = 96mm^2.
C=2πr
C=πd
A=πr^2
r=C/2π
r=1/2 d
<u>By the way all you do to solve r is: </u>
C=2πr
C/2π=2πr/2π
C/2π=r
r=C/2π
Hope this helps:)
Answer:
As to sidea are equal therefore it is an isosceles triangle .
therefore
,80+x+x=180
80+2x=180
2x=100
x=50
