2x⁴ + (-3x²)² + 10(x²)² + (-3x²)²

2x⁴ + (9x⁴) + 10 (x⁴) + (9x⁴)

2x⁴ + 9x⁴ + 10x⁴ + 9x⁴

2x⁴ + 10x⁴ 9x⁴ + 9x⁴

12x⁴ + 18x⁴

30x⁴

(-x)² = x²

Wilbur runs 3.2 km every morning how many feet are in 3.2 km given that 1 mile = 1.609 km and 1 mile = 5,280

Nonamiya [84]

1.609/5280 = 3.2/x....1.609 km to 5380 ft = 3.2 km to x ft
cross multiply because this is a proportion
(1.609)(x) = (5280)(3.2)
1.609x = 16896
x = 16896/1.609
x = 10,500 ft <===
