Step-by-step explanation:

2( l + w ) = perimeter of triangle

P = 2( 10+8 )

p= 2(18)

p= 36cm

Circle = pie (r) + d. recall d = 2r

P= 3.142 (4) + 8

P= 20.57~

so therefore= , 36 + 2(20.57)= 77.14cm ~ to the nearest tenths

8c=5c+21 What would that be
NemiM [27]
To solve for C, you have to get both of the numbers with a C on the same side.  So, subtract the 5c from the right side onto the left side.

8c = 5c + 21\\8c - 5c = 5c - 5c + 21\\3c = 21

Then, divide by 3 on each side.

3c = 21\\3c /3 = 21/3\\c = 7

So, c = 7.
