Alicia is sewing a rectangle bedspread that measures 72 inches by 60 inches. The bedspread is red with a gold circle 18 inches i
Natalija [7]

Answer:

4,066\ in^{2}

Step-by-step explanation:

we know that

The area of the bedspread that is red is equal to the area of rectangle minus the area of the circle

step 1

Find the area of rectangle

The area is equal to

A=72*60=4,320\ in^{2}

step 2

Find the area of the circle

A=\pi r^{2}

we have

r=18/2=9\ in ----> the radius is half the diameter

assume

\pi=3.14

substitute

A=(3.14)(9)^{2}

A=254.34\ in^{2}

step 3

Find the area of the bedspread that is red

Find the difference of the areas

4,320\ in^{2}-254.34\ in^{2}=4,066\ in^{2}

I think... J because
x + 1 / x^3 - x
Factor out x from the expression
x + 1 / xx(x^2 - 1)
Use a^2 - b^2 = (a - b)(a + b) to factor the expression
x + 1 / x • (x - 1) • (x + 1)
Reduce the fraction with x+ 1
1 / x • (x - 1)
Distribute x through the parentheses
1 / x^2 - x
