Answer:
Finding Length and Width When You Know Area and Perimeter
If you happen to know the distance around the rectangle, which is its perimeter, you can solve a pair of equations for L and W. The first equation is that for area, A = L ⋅ W, and the second is that for perimeter, P = 2L + 2W

Answer:
B
Step-by-step explanation:
When adding two matrices of the same dimensions we addup each two corresponding elements of these matrices:
![A+B=\left[\begin{array}{cc}8&-3\\3&y+2\end{array}\right]+\left[\begin{array}{cc}3x&z+4\\w&\frac{1}{2}y\end{array}\right]=\left[\begin{array}{cc}8+3x&-3+z+4\\3+w&y+2+\frac{1}{2}y\end{array}\right].](https://tex.z-dn.net/?f=A%2BB%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D8%26-3%5C%5C3%26y%2B2%5Cend%7Barray%7D%5Cright%5D%2B%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D3x%26z%2B4%5C%5Cw%26%5Cfrac%7B1%7D%7B2%7Dy%5Cend%7Barray%7D%5Cright%5D%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D8%2B3x%26-3%2Bz%2B4%5C%5C3%2Bw%26y%2B2%2B%5Cfrac%7B1%7D%7B2%7Dy%5Cend%7Barray%7D%5Cright%5D.)
When two matrices are equal, then corresponding elements are equal:
Hence,
![B=\left[\begin{array}{cc}-12&5\\1&-2\end{array}\right].](https://tex.z-dn.net/?f=B%3D%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D-12%265%5C%5C1%26-2%5Cend%7Barray%7D%5Cright%5D.)
Answer:
700members
Step-by-step explanation:
36%=252
100%=?
100×252/36
=700
Its to scale. so every inch is 1.5 feet according to the statement of 18 inches being equal to 27 feet. In that case, the answer is C. because 20X1.5 is 30
We are given with
250 N force
F = 250 N
The usual monkey wrench has a length of 11 cm or 0.11 m
d = 0.11
Therefore, the moment is
M = F d
M = 250 (0.11) = 27.5 N m
