Mathematics
1 answer:

Answer:

Length= 50

Width=17

Step-by-step explanation:

length= n+8

Since n= 42, Just plug it in. So it would be 42+8 which is 50 for the length

Widith: 1/2n-4

basically since N is given for 42, you do 1/2 multipied by 42 which is 21.

Since you also have to subtract 4 inches it would be 17 for the length

In the magic square shown, the sums of the numbers in each row, column and diagonal are the same. What are the values of x, y, z
garri49 [273]
v=23, w=19, x=22, y=26, z=20;; to find the answer, set the expressions equal to each other, since the sum of the numbers should be the same.

Use v+w+24=v+43 and solve for w, which would result in w=19.

You can also use x+z+24=z+46 to find x– or x=22.

Plug in the values for x and w, and find y using 25+22+19=y+40 or 66=y+40 and results in y=26.

After plugging in the y value, you can easily find v and z.

v+18+25=66– since 66 is the sum of a full row, and the sums of the numbers in each row, column, and diagonal are the same, so therefore, v+43 should also equal 66. This results in v=23, and, using the same value for the sum of z+21+25, or z+46=66, we find that z=20.

The final answer is v=23, w=19, x=22, y=26, z=20.

Sorry it took so long;; I hope this helps :)
