Answer:
The first one is KL and the second one is FG
Step-by-step explanation
The E3 is the same as writing 10^3.
The answer would be 7.9 x 10^3
Assume that the other number is y.
we know that the addition of both number is -9
this means that:
x+y=-9
reorder this equation to seperate the y variable:
y=-9-x
Step-by-step explanation:
3r + (9 + 2r + 1)
this can be simplified :
3r + (9 + 2r + 1) = 3r + 2r + 9 + 1 = 5r + 10
