S= (pi times r times l) + (pi times radius squared)
Factor out the pi times r
S= (pi times r) l + r
Divide
S/(pi times r)= l + r
Find common denominator and subtract
(S- pi times r)/(pi times r) = l
The answer therefore is A
Answer:
x = - 7
Step-by-step explanation:
Given
4(1 - x) + 2x = - 3(x + 1) ← distribute parenthesis on both sides
4 - 4x + 2x = - 3x - 3, that is
4 - 2x = - 3x - 3 ( add 3x to both sides )
4 + x = - 3 ( subtract 4 from both sides )
x = - 7
Answer:
-2.5
Step-by-step explanation:
