Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

7*x-4-(21)=0

Solve  :    7x-25 = 0

Add 25 to both sides of the equation :

                     7x = 25

Divide both sides of the equation by 7:

                    x = 25/7 = 3.571

Answer:

35

Step-by-step explanation:

The area of a sector of a circle is given by the formula ...

  A = (1/2)r²θ

where r is the radius and θ is the central angle in radians.

For your sector, the area is ...

  A = (1/2)(5 in)²(1/2) = 25/4 in²

Can someone help pls!!
kari74 [83]

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.
