The area of a rectangle is 192 in squared. the ratio of the length to the width is 4 : 3. find the length and the width.

L = 16 inches , W = 12 inches

Step-by-step explanation:

Area = 192

Ratio of length to the width = 4 : 3

This means that  L = W  

Area of a rectangle = Length x width

Substituting A = 192 and L = W into the formula for calculating area of rectangle , we have

192 = W x W

192 =

192 X 3 =

576 =

Divide through by 4

144 =

Take the square root of both sides

Therefore :

W = 12 inches

Substitute W = 12 into  L = 4/3W , which means

L = 4/3 X 12

L = 16 inches

Therefore :

Length = 16 inches and Width = 12 inches

on your paper it doesn't say the answer but the the answer is altitude

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
