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

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

alexandr402 [8]

Answer:

$x < - 1$

You should have a circle on -1 with the arrow going left

Step-by-step explanation:

Subtract 8 from both sides.

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

$- 4x > 4$

Divide by -4

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

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

$x < - 1$
