Answer:
x = 12
Step-by-step explanation:
Equation: 0.52(x) + 0.72(4) = 0.57(x + 4)
0.52(x) + 0.72(4) = 0.57(x + 4)
Multiply
0.52x + 2.88 = 0.57x + 2.28
Subtract 0.52x from both sides
2.88 = 0.05x + 2.28
Subtract 2.28 from both sides
0.6 = 0.05x
Divide all sides by 0.05
x = 12

Answer:
Circumference: 37.68
Area: 113.04
Step-by-step explanation:
the formula to find the circumference is 2 x 3.14 x r
r is the radius so you plug in 6 for that
2 x 3.14 x 6 = 37.68
the formula to find the area of a circle is 3.14 x r ²
r is still the radius so you plug in 6 for that
3.14 x 6² = 113.04
5m+2m+2 = 23
7m=21 , So:: m=21:7
m=3
