STEPS :

(8m + 7) ^ 2  
Apply distributing rule : (a + b)^2 = a^2 + 2ab + b^2

= (8m)^2 + 2 ⋅ 8m <span>⋅ 7 + 7^2
</span>   (8m)^2 = 64m^2
   2 ⋅ 8m <span>⋅ 7 = 112m
</span>   7^2 = 49

= 64m^2 + 112m + 49

Hope this helps :)

Michael and Landon work at a dry cleaners ironing shirts. Michael can iron 40 shirts per hour, and Landon can iron 20 shirts per
BartSMP [9]

Answer:

Michael worked 4 hours and Landon worked 10 hours.

Step-by-step explanation:

Michael can iron 40 shirts each hour, so in xx hours he can iron 40x40x shirts. Landon can iron 20 shirts each hour, so in yy hours he can iron 20y20y shirts. The total number of shirts ironed 40x+20y equals 360:

40x+20y=360

40x+20y=360

Since Michael and Landon worked a combined 14 hours, we know x+yx+y must equal 14.

x+y=14

Write System of Equations:

​

40x+20y= 360

x+y=14

Solve for y in each equation:

​

40x+20y = 360  x+y = 14 20y = -40x+360  

\frac{-20y}{20} =\frac{-40x+360}{20}

y = -2x+18

Select the correct answer.<br> A and АВ:<br><br> Which matrix is matrix B?
Kruka [31]

Answer:

Option B

Step-by-step explanation:

Looking at the options, option B is correct because when multiplying it by matrix A, it yields the matrix AB as follows;

First row of A multiplied by first column of matrix in option D;

(1 × -1) + (0 × 0) + (0 × 0) = -1 which corresponds to the first number on the first row of Matrix AB

Since majority of matrix AB are zero, I will just prove the ones that are not zero.

Thus;

Second row of matrix A is multiplied by second column of matrix in option D;

(0 × 0) + (-1 × -1) + (0 × 0) = 1 which is same as 2nd number on second row in matrix AB

Lastly, third row of matrix A is multiplied by third column of matrix in option D;

(0 × 0) + (0 × 0) + (1 × -1) = -1 which is same as third number in third row in matrix AB
