Answer:
Step-by-step explanation:
A + G + M = 740
A = G - 20
A = M - 120
Therefore,
G = A + 20
M = A + 120
Plug it in...
A + (A + 20) + (A + 120) = 740
Combine like terms
3A + 140 = 740
- 140 -140
3A = 600
/3 /3
A = 200
Double check
A = 200, G = 220, M = 320
200 + 220 + 320 = 740

Answer:
48+14i
Step-by-step explanation:
So squaring (i+7) looks like this
(i+7)^2
(i+7)(i+7)
Use foil.
First: i(i)=i^2=-1
Outer: i(7)=7i
Inner: 7(i)=7i
Last: 7(7)=49
____________Add the terms.
48+14i
Answer: 7+0.7+0.05
Since 7 is in the ones place it goes in front of the decimal. .7 is in the tenth place because it's behind the decimal. .05 is also behind the decimal so it's in the hundredths place.
