Answer:
96b-60
Step-by-step explanation:
12(8b-5)=
12*8b - 5*12 =
96b-60
The formula for surface area are 2(LW+LH+WH). If the numbers were being placed in the formula, it will become 2[(9*7)+(9*12)+(12*7)]. 9*7 is 63, 9*12 is 108, 12*7 is 84 and the sum will be 255, and multiply by 2 is 510.
The answer is 510
40×20=? that's your answer
ps.its 800cm/m 3
The system of equations has no solution.
Solution:
Given expression –x + 5y = 5 and x – 5y = 5.
–x + 5y = 5 – – – – (1)
x – 5y = 5 – – – – (2)
Adding (1) and (2), we get
–x + 5y + x – 5y = 5 + 5
Combine like terms together.
(–x + x) + (5y – 5y) = 5 + 5
0 + 0 = 25
There is no x-term and y-term in Left hand side.
So, the system of equations has no solution.
