alexira [117]

Answer:

784 in²

Step-by-step explanation:

Let the original side is x.

1 foot = 12 inches

New sides of a rectangle are:

x + 12 and x - 4

The area of rectangle is:

(x + 12)(x - 4) = 960

Solve for x:

x² + 8x - 48 = 960
x² + 2*4*x + 16 - 64 = 960
(x + 4)² = 1024
x + 4 = 32
x = 28

Area of the original blanket:

A = 28² = 784 in²

One third of the candidates for a job were 25 years old or younger. two sevenths of the candidates were at least 50 years old. i

Shalnov [3]

There are three groups of people: 25 years old and younger, between 25 to 50, and 50 years old and older. Their fractions must equal to 1 because these three together form the whole.

1 = 1/3 + 2/7 + x
where x is the fraction for people ages 25 to 50 years old
x = 8/21

So, the actual number of people ages 25 to 50 years old is:

84(8/21) = 32 people

x(y-3)=40

y-3=(40/x)

y=(40/x)+3

y=(40/5)+3
