<span>6x=480 ft
x=80 ft.
Area = x^2 = 80^2 = 6400 sq. ft.</span>
First you would have to multiply (1200)(3%)(7) which would be 252.then you add what jamie invested and 252. therefore she would have $1452 in his account after 7 years.
Answer:
63
Step-by-step explanation:

divide, 27 ÷ 3
you'll get 9, so
x = 9
Next part
5y = 35
divide both sides by 5 to isolate y,
5y ÷ 5 = 35 ÷ 5
=
y = 7
So
x = 9 and y = 7
Then let's add the numbers to our equation ( x × y)
9 × 7
=
63
Answer:
The Third one
Step-by-step explanation:
Because the y is not included in the function ( see some lines ) and x is the same thing but it is larger than -3 and it is included in the function .
I hope that it's a clear solution and explanation.
