Answer:
x^2 +4x -21
Step-by-step explanation:
Substitute the given expressions and simplify.
f(x) + g(x)
= (x^2 +3x -28) +(x +7)
= x^2 +(3+1)x +(-28 +7)
= x^2 +4x -21
Answer: 17.49 = L or 17 1/2 = L
Step-by-step explanation:

Answer:I think 57Step-by-step explanation:
Cuz its adding 2 every time then I just did 28 x 2 and added the extra. Does that make sense?
4 x 8 = 28
28 x 2 = 56
56 + 1 = 57
The answer to number 1 is 16, because it the equation would be simplified to this...
32 + 4 - 20 = 36 - 20 = 16
The 3rd answer is 551...
(-125+11)(-5)-19=579-19=551
The 5th answer is 29383...
-17×1728=29383...
Hope this helps!!!
Answer:
$33
Step-by-step explanation:
First we calculate the cost of the overdrafts:
3 overdrafts * $35 = $105
Then, if he maintains an average monthly balance of $600, we can calculate = $600*12 months = $7200 (average yearly balance). And the bank pays him 1% interest per annum:
$7200 * 1% = $72 (this is what the bank pays the graduate per year)
So if the bank charges him $105 and pays him $72, then the net annual cost is = $105-$72= $33
