no, the have a negative difference
The answer wouls be 18 because you replace r with 7 and the your equation becomes 11+7 which equals 18
Area of large triangle
= 1/2 bh
= 1/2 (5)(12)
= 1/2 (60)
= 30
area of un-shaded triangle
= 1/2bh
= 1/2(3)(4)
= 1/2 (12)
= 6
area of shaded = area of large triangle - area of un-shaded triangle
area of shaded = 30 - 6
area of shaded = 24
answer
24
Assuming that the interest rate in each case is the same, the only factors that come into play are the length of time, and the accessibility of the money. The longer the money is left alone, the more money it will accrue, meaning the first option "saving for retirement in 20 years" is the best option. The two below it are a shorter length of time and will therefore accrue less, and the final option is less profitable because withdrawing from the account would decrease the total interest earned.
