Answer:
−s2+2st−t2−s+t
Step-by-step explanation:
−(s−t)−(s−t)2
distributed would be
−s+t+−s2+2st+−t2
Remember the formula for volume is area multiply by height so do that
Angle 1 is 107°, and the other one is 73° (180-107=73)
0.0000009
.9 times 10 is 9, so then you have to move it back -6 times behind the decimal.
