Let number=x
(X/2)+6=8
First subtract 6 on each side to isolate X on one side.
(X/2)=2
Now to fully isolate X by itself, just multiply 2 on each side.
X=4
Pythagorean Theorem A2+B2=C2
625=25+C2
600=C2
Square root of 2 each side
10 Square root of 6 Or 24.494897
18 would be the 7th so... hope it helps
56 + 41 + x = 180
97 + x = 180
x = 180 - 97
x = 83 <==
We can notice from the figure that : Area of the home plate is equal to sum of the Area of the rectangle ( 8 in x 15 in) and Area of the triangle with height 6 in and base 15 in.
Area of the rectangle : Length x Width
⇒ Area of the rectangle = 15 x 8 = 120 in²
Area of the triangle : 1/2 x Base x Height
⇒ Area of the triangle = 1/2 x 15 x 6 = 45 in²
Area of the home plate = Area of rectangle + Area of triangle
⇒ Area of the home plate = 120 in² + 45 in² = 165 in²
<u>Answer</u> : D
