Answer: 42.14 cm^2

square:

Area of a square=s^2
A=14^2
A=196

circle (the two semi circles are the same as one circle):

Area of a circle=(pi)(r)^2

divide 14 (diameter) by 2 to find the radius

A=(3.14)(7)^2
A=(3.14)(49)
A=153.86

subtract the area of the two semi circles from the area of the square to get the answer

196-153.86=42.14

Part 7 math work 10th-grade work
Irina-Kira [14]

Answer:

x>11 is the solution to both equations.

Step-by-step explanation:

I apologize for late response I've been busy lately. Anyways here ya go! :

From what I understand it wants us to solve "9x-4>95" so that's what I'll do.

add 4 to each side

9x>99

divide each side by 9

x>11 is the solution to 9x-4>95

For 4x+10>54

subtract 10 from each side

4x>44

divide each side by 4

x>11 is the solution to 4x+10>54
