I believe the answer is 800
Answer:
29
Step-by-step explanation:
(5+1)^2-(12+3^2)/3 Add 5 and 1 = 6.
6^2-12+3^2/3 Calculate 6 to the power of 2 = 36.
36-12+3^2/3 Calculate 3 to the power of 2 = 9.
36-12+9/3 Add 12 and 9 = 21.
36-21/3 Divide 21 by 3 = 7.
36−7 Subtract 7 from 36 to get 29.
Let amount invested at 8% per year = x
Let amount invested at 14% per year = y
Total investment is $94000 then we get equation:
x+y=94000
or
x=94000-y...(i)
Given that total return in 1 year is $8720 so we can write equation:
8% of x + 14% of y = 8720
or
0.08x+0.14y=8720...(ii)
plug (i) into (ii)
0.08(94000-y)+0.14y=8720
7520-0.08y+0.14y=8720
7520+0.06y=8720
0.06y=8720-7520
0.06y=1200
y=20000
plug value of y into (i)
x=94000-y=94000-20000=74000
Hence final answer is given by:
Amount invested at 8% per year = $74000
Amount invested at 14% per year = $20000
-3 im am sure its correct
Answer:
Step-by-step explanation:
Givens
Length = a
Width = a + 3
Formulas
P = 2L + 2w
Area = L * w
Solution
Perimeter
P = 2L + 2w
P = 2*a + 2(a + 3) Remove the Brackets
p = 2a + 2a + 6 Combine
<u><em>P = 4a + 6</em></u>
Area
Area = L * w
Area = a (a + 3)
<u><em>Area = a^2 + 3a</em></u>
