Answer:
1 solution
Step-by-step explanation:
-6y + 13 + 9y = 8y - 3
=> 3y - 8y = -3 - 13
=> -5y = -16
=> y = 16/5
so y= 16/5 or 3.20

Answer:
64 + 64sqrt(3)
174.9 cm²
Step-by-step explanation:
AD/2 = 8cos(60) = 4
AD = 8 cm
Height of each triangle = 8sin(60)
= 4sqrt(3)
sqrt: square root
Area = 8² + 4(½ × 8 × 4sqrt(3))
= 64 + 64sqrt(3) cm²
= 174.8512517 cm²
