Answer:

The number of sides is 7

Step-by-step explanation:

Once the sum of interior angles is equal to 900º and the sum of interior angles is given by

S=(n-2) \cdot 180\º, \text{ as }n \text{ being the number of sides}

900\º = (n-2) \cdot 180\º

\dfrac{900\º}{180\º}  = (n-2)

5 = (n-2)

5+2 = n-2+2

\boxed{n=7}

The length of a living room is 12 feet and its width is 1012 feet. The length of the room is being expanded by x feet. Choose an
Ivanshal [37]

Answer:

Option C. 10.5(12 + x) square feet

Option E. (126 + 10.5x) square feet

Step-by-step explanation:

step 1

Find the area of the original living room

we know that

The area of the original living room is equal to

A=LW

we have

L=12\ ft\\W=10\frac{1}{2}\ ft=10.5\ ft

substitute

A=(12)(10.5)=126\ ft^2

step 2

Find the new area of the living room

The length of the room is being expanded by x feet

so

we have

L=(12+x)\ ft\\W=10.5\ ft

The new area is

A=10.5(12+x)\ ft^2

The expanded form of the expression is

Apply distributive property

A=10.5(12)+10.5(x)\\A=(126+10.5x)\ ft^2

What’s is the radius of a circle with a area of 3.21 square feet
Rus_ich [418]

approx 1 foot

The area (A) of a circle = πr² ( where r is the radius)

thus r² = A/π ⇒ r = √(A/π = √(3.21/π) =1.0108..... ≈ 1 foot ( to 1 dec. place)
