Answer:
C) 42.14 cm²
Step-by-step explanation:
<u>Recall the area formulas for a square and circle:</u>
Area of square: A=s²
Area of circle: A=πr²
<u>Given:</u>
π=3.14
s=14
r=s/2=14/2=7
Therefore, the area of the square is A=14²=196 cm²
The area of the two semicircles is A=3.14(7)²=3.14(49)=153.86 cm²
Find the difference between the two areas to get the shaded area:
196 - 153.86 = 42.14
Therefore, the shaded area is 42.14 cm², making C the correct choice.

9+-8=1
Answer:
C. y = -9, -3, 0, 5, 7
Step-by-step explanation:
The given function is represented by the set of ordered pairs
{(-2,0,) (-4, -3,) (2, -9,) (0,5,) (-5,7)}
The range of this function is the set of all the y-values.
The set of the y-values are:
{-9,-3,0,5,7}
Therefore the range is y = -9, -3, 0, 5, 7
The correct option is C
Step-by-step explanation:
x² + 2x
x(x + 2)
<u>OR</u>
x² + 2x = 0
x(x + 2) = 0
x = 0 or x + 2 = 0
x = 0 or x = - 2
