Answer:
-10n - 60
Step-by-step explanation:
Use the distributive property to simplify [ a(b + c) = ab + ac ]
-10(n + 6)
(-10 * n) + (-10 * 6)
-10n + -60
-10n - 60
Best of Luck!
Step-by-step explanation:
A = (1/2)bh ---> h = 2A/b = 2(12 cm^2)/(5 cm) = 4.80 cm
---> x^2 = h^2 + (b/2)^2
= (4.8 cm)^2 + (2.5)^2
= 23.04 cm^2 + 6.25 cm^2
or x = 5.41 cm
Therefore, the perimeter P is
P = 2x + b = 2(5.41 cm) + 5 cm = 15.8 cm
