Salut!
Ai ca a + b + c +d = 600;
a = b + 12 => b = a-12;
a = c - 12 => c = a + 12;
d = (a+b+c)/3 => d = a;
In final, 4a = 600 => a = 150;
b = 138;
c = 162;
d = 150;
Bafta!
Answer:
x = - 
Step-by-step explanation:
Given
- 2(4x + 3) = 3(x + 1) ← distribute parenthesis on both sides
- 8x - 6 = 3x + 3 ( subtract 3x from both sides )
- 11x - 6 = 3 ( add 6 to both sides )
- 11x = 9 ( divide both sides by - 11 )
x = - 
If two chords intersect each other inside a circle, the products of their segments are equal.
7(n+4) = 5(n+8)
7n + 28 = 5n + 40
7n - 5n = 40 - 28
2n = 12
n = 6
