Answer:

x² + 8x + 7

Step-by-step explanation:

( x + 1 ) ( x + 7 )

Formula : -

( a + b ) ( a + c ) = a² + ( b + c )a + bc

Here,

a = x

b = 1

c = 7

( x + 1 ) ( x + 7 )

= x² + ( 1 + 7 )x + 1 * 7

= x² + 8x + 7

A clock face has a diameter of 10 inches. What is the area of the clock face?
sleet_krkn [62]

Answer:

A = 78.5 in ^2

Step-by-step explanation:

Area of a circle = pi * r^2

The radius is d/2

r= 10/2

r =5

A = pi * r^2

Substitute r=5

A = pi *(5)^2

A = 25 pi

We know that pi is approximated by 3.14

A = 25 (3.14)

A = 78.5 in ^2
