What is the length and the width of a rectangle with perimeter of 48 inches if its length is 7 inches longer than its width.
sattari [20]

Answer:

Length and the width of the rectangle is 15.5 inches and 8.5 inches respectively.

Step-by-step explanation:

Given:

Length = 7 inches + Width

=> P = 48 inches

=> L = (7 + W) inches............. (1)

Perimeter 'P' is the sum of all sides of the rectangle 2 (L + W)

∴ 48 inches = 2 (L + W) .................(2)

Substitute for L in equation (2)

∴ 48 inches = 2 [(7 + W) + W]

48 = 2[7 + 2W]

48 = 14 +4W

48 - 14 = 4W

34 = 4W

W = 8.5 inches

Recall that: Length, L = (7 + W)

∴ L = (7 + 8.5)

L = 15.5 inches

MAXImum [283]

Answer:

There are a total of 4 + r + 6 marbles in the bag

The probability of a blue is  \frac{4}{10+r}  

The probability of a red is  \frac{r}{10+r}  

The probability of choosing a blue, replacing it and then a red is

\frac{4}{10+r} × \frac{r}{10+r}  =  [tex]\frac{4r}{100+20r+ r^{2} /[tex]
