Answer:
a = 9 meters
Step-by-step explanation:
The perimeter is the sum of the side lengths:
28 m = a + 2m + a + 8m
18 m = 2a . . . . . . . . . . . . . . . . subtract 10m, collect terms
9 m = a . . . . . . . . . . . . . . . divide by 2
The value of a is 9 meters.
-3*10= -30 to the 4th power is 810,000
10 to the -3 power is -1000 * 2 is -2000
810,000 * -2000 = -1,620,000,000
