Answer:
592 in²
Step-by-step explanation:
Given
Length of the box L = 12 inches
Width W = 8 inches
height H = 10inches
Required
Surface Area of the box
Surface area of the rectangular boss = 2(LW + LH + WH)
Substitute the given values
Surface area = 2(12(8)+12(10)+8(10))
Surface Area = 2(96+120+80)
Surface Area = 2(96+200)
Surface area = 2(296)
Surface area = 592 in²
Hence 592 in² of wood would be needed by Mitchell to build the box
Answer:
The answer is c :" Mary should isolate the x term because she can then simplify the remaining expression to solve for x."
Step-by-step explanation:
From the equation as written below,
(x-4)(x-1)= 60
the first step is expansion of the bracket, thus we have,
x2-4x-x+4=3(2)60
which equals
x2-5x+4=3(2)60
then the next step should be to isolate x terms to be on one side of the equation while she continues solving for x,
x2-5x= 3(2)60-4
This is because in such simple equations, x could only be found if all terms of x are isolated in one side of the equation before continuing other processes such as factorization,etc.
The answer is b just because inequality
Answer:
A
Step-by-step explanation:
z = -3 - 5i
z (i) = i (-3 - 5 i)
z (i) = -3i - 5i^2
z (i) = -3i - 5 (-1)
z (i) = -3i + 5
z (i) = 5 - 3i
Therefore, letter A is the correct answer.
The answer is not defined.
Explanation:
The given matrix is ![$\left[\begin{array}{cc}{2} & {4} \\ {1} & {-6}\end{array}\right]+\left[\begin{array}{c}{1} \\ {0}\end{array}\right]$](https://tex.z-dn.net/?f=%24%5Cleft%5B%5Cbegin%7Barray%7D%7Bcc%7D%7B2%7D%20%26%20%7B4%7D%20%5C%5C%20%7B1%7D%20%26%20%7B-6%7D%5Cend%7Barray%7D%5Cright%5D%2B%5Cleft%5B%5Cbegin%7Barray%7D%7Bc%7D%7B1%7D%20%5C%5C%20%7B0%7D%5Cend%7Barray%7D%5Cright%5D%24)
The matrix
has dimensions ![2\times 2](https://tex.z-dn.net/?f=2%5Ctimes%202)
This means that the matrix has 2 rows and 2 columns.
Also, the matrix
has dimensions ![2\times1](https://tex.z-dn.net/?f=2%5Ctimes1)
This means that the matrix has 2 rows and 1 column.
Since, the matrices can be added only if they have the same dimensions.
In other words, to add the matrices, the two matrices must have the same number of rows and same number of columns.
Since, the dimensions of the two matrices are not equal, the addition of these two matrices is not possible.
Hence, the addition of these two matrices is not defined.
