dimulka [17.4K]

Answer:

53\frac{1}{2}\ in

Step-by-step explanation:

we know that

The perimeter of a square is equal to

P=4a

where

a is the length side of the square

in this problem we have

a=11\frac{3}{8}\ in

convert to an improper fraction

11\frac{3}{8}\ in=\frac{11*8+3}{8}=\frac{91}{8}\ in

Find the perimeter of the square

P=4\frac{91}{8}=45.5\ in

Remember to adds two extra inches for each corner

so

The wood needed is  

45.5\ in+2*4\ in= 53.5\ in

convert to mixed number

53.5\ in=53\frac{1}{2}\ in

Choose the graph of the inequality's solution. -4x + 8 > 12

- 4x + 8 > 12 \\  - 8 \:  \:  \:  \:  - 8

- 4x > 4

Divide by -4

\frac{ - 4x}{ - 4}   >  \frac{4}{ - 4}

Since you are dividing by a negative, you need to flip the inequality.

x <  - 1
