Formula for sufrace area of rectangular prisms: S= 2 (lw + lh + wh)
for the first prism, x=14, plug 14 into 2(x)--> 2(14)=28
7,8,28
S= 2 [7(8)+7(28)+8(28)]
S= 2 (28+196+224)
S= 2(448)
S= 896
for the second prism, x is just 14
7,8,14
S= 2 [7(8)+7(14)+8(14)]
S= 2 (28+98+112)
S= 2(238)
S= 476
Add the two sufrace areas we found and the answer will be
D) S= 1,372

72 multiplied by 6 equals 432
Answer:
n = 3
Step-by-step explanation:
8n - (3n + 4) = 11
8n - 3n - 4 = 11
5n = 11 + 4
5n = 15
n = 3
The amount Sheila deposits in the Bank of US saving account is $511.
Sabrina has a total of $3,066 she wants to deposit. She has three banks that she wants to deposit her money in.
Let, a represent the amount she would deposit she would invest 7/4 bank.
The amount invested in Catch bank = 6 x a = 6a
The amount invested in Bank of US = 20% x ( 6a + a)
= 0.2 x 7a
= 1.4a
The total amount invested in the three banks can be represented with this equation:
1.4a + a + 6a = 3066
In order to determine the amount she would save in the Bank of US, the amount deposited in 7/4 bank has to be determined first.
8.4a = 3066
a = $365
The amount deposited in the Bank of US = 1.4a
= 1.4 x 365
= $511
