Answer:
a = 8√2
Step-by-step explanation:
a² + b² = c²
a² +14² = 18²
a² + 196 = 324
Subtract 196 from both side
a² = 128
Take the square root of both sides
a = √128
a = √(64 * 2)
a = 8√2

solve for "r", to see what the radius is
keep in mind that, the diameter is just "2r"
We know that the area of a rectangle is equal to the width multiplied by the length. So in this case the algebraic expression is (x+5)*(3x+10). You get 3x^2 +10x +15x +50= 3x^2 +25x +50.
