Answer:

Step-by-step explanation:

Diameter=5 inches

Area= π $r^{2}$

<u>r is the radius of coaster.</u>

<u>Radius=diameter/2</u>

Substitute the value of D:

r=5/2

Now

Area=π $\frac{5}{2} ^{2}$

Area=π( $\frac{25}{2}$ )

Area=12.5π sq.inches

What is the solution to this equation? x + (- 14) = 4. (A) x = 10. (B) x = - 10. (C) x = - 18. (D) x = 18

Vika [28.1K]

First, you want to get x by itself on one side. We write the equation as $x-14=4$ . Since 14 is being subtracted from $x$ , we add it to both sides to cancel it out, $x-14+14=4+14$ or $x=18$ .

Your answer would be D.
