The length of a rectangle is 12x + 7 and the width is 6x – 5. Jason cut a square with side length of (x + 2) from the rectangle. Which expression represents the remaining area of the original rectangle?

The remaining area of the original rectangle can be expressed as: length = 11x + 5 & width = 5x - 7

Step-by-step explanation:

Jason cut a square out of a rectangle which means the new rectangle will be smaller than the original one. To find the new length and width of the rectangle, we subtract (x + 2) from the original length and width respectively. So we'll have:

When you expand and open the bracket, (x + 2) will become - x - 2. Now, collect like terms:

The new length will be = 11x + 5

To find the new width of the rectangle, we'll have:

So we have (5x - 7) as the new width.

percentage - 25%

probability - 0.25

we know,

total amount of students in class = 20

total boys = 10

total girls = 10

no of girls who wear glasses = 10/2 = 5

probability of choosing a girl with glasses is =

number of girls wearing glasses/total number of students in the class = 5/20

thus, percentage of selecting a girl wearing glasses will be

= 5/20 × 100

= 5 × 5

25%

therefore,

probability will be 0.25
