If you drove for 425 miles at 60 mph, you would get there in 7 hours and 8-ish minutes. 425 divided by 60 is 7.08333333333333.
15) 4m^2
17)9n^6
198a^2 (^ = power of)
(x - 8)² = 144
Take square root of both sides
(x - 8) = √144
x - 8 = 12
x = 12 + 8
x = 20
Original lawn is = 20 feet * 20 feet square
Answer:
x ≈ 61.3
Step-by-step explanation:
Using the Sine rule, that is
=
( cross- multiply )
5.8 × sinx = 6 × sin58° ( divide both sides by 5.8 )
sin x =
≈ 0.87729, thus
x =
(0.87729) ≈ 61.3
2(20+60+48)=2(128)= 256 square inches
