Answer:
-71
Step-by-step explanation:
let 'n' = a number
2(143 + 2n) = 0n + 2
2(143 + 2n) = 2
143 + 2n = 1
2n = -142
n = -71
-10x + 48 = -6x+24
48 - 24 = -6x + 10x
24 = 4x
x = 24/4
x = 6
Hello :
<span> the equation of the circle is (x-a)²+(y-b)² = r²
A(a;b) center r : </span><span>radius
</span>in this exercice : (x+3)²+y²=25
.2 converted to a fraction would be 1/5
