Step-by-step explanation:
Area of circle = π × r²
→ 123 = π × r²

Answer:
1) x=2
Step-by-step explanation:
1) 3(2x+1)=15
simplify both sides of the equation
3(2x+1)=15
(3)(2x)+(3)(1)=15 (distribute)
6x+3=15
subtract 3 from both sides
6x+3 -<em>3 </em>=15-<em>3</em>
<em>6x=12</em>
<em>divide both sides by 6</em>
<em>6x/6 = 12/6 </em>
<em>x=2 </em>
