Find the area of this shape *
Lyrx [107]

Answer:

134.1 ft²

Step-by-step explanation:

<u>Fine the area of the square first, then subtract the area of the circle to find the area of the shaded part.</u>

The area of the square

= 25²

= 625 ft²

The radius of the circle

= 25 ÷ 2

= 12.5 ft

The area of the circle

= π × 12.5²

= 490.87385...

= 490.9 ft² (rounded up to the nearest tenth)

The area of the shaded part

= 625 - 490.9

= <u>134.1 ft²</u>

Which graph represents the solution set for the quadratic inequality x2 + 2x + 1 &gt; 0
AnnyKZ [126]

we have

x^{2}+2x + 1 > 0

we know that

x^{2}+2x+1=(x+1)^{2}

so

(x+1)^{2}> 0

two solutions

<u>first solution </u>

(x+1)> 0

x > -1

the first solution is the interval---------> (-1,∞)

<u>second solution</u>

-(x+1)> 0

-x-1> 0

-x> 1

x< -1

the second solution is the interval---------> (-∞,-1)

therefore

the solution is all real numbers except the number -1
