Answer:

2A/ (b1-b2) =h

Step-by-step explanation:

A = 1/2 (b1-b2) *h

Multiply each side by 2

2A = 2 *1/2*(b1-b2) *h

2A = (b1-b2) *h

Divide by (b1-b2)

2A/ (b1-b2) = (b1-b2)/(b1-b2) *h

2A/ (b1-b2) =h

a diver is swimming at -10 m. He then descends 3m and rises 6m. At what new level is the diver swimming?

iVinArrow [24]

So we start at -10. Because he descends 3 feet, We subtract 3, getting -13. He then rises 6 feet. -13 + 6 = -7. The diver is now at -7 feet.
