Answer:
Step-by-step explanation:
x² + 4y² = 36
divide by constant
x²/36 + y²/9 = 1
x²/6² + y²/3² = 1
6>3, so length of major axis is 2×6 = 12
128 = 2^7 = 2*(2^3)^2
sqrt(128) = sqrt(2*(2^3)^2) = 2^3*sqrt(2)
You can't reduce this fraction any more than it already is:)
1 m = 1.5 ft
1 sec = 0.025 ft
1 hour = 90 ft
